Always, always, the sine of an angle is equal to the opposite side divided by the hypotenuse (opp/hyp in the diagram). The cosine is equal to the adjacent side divided by the hypotenuse (adj/hyp).
Is SEC Adj over HYP?
sin(q) = opp/hypcsc(q) = 1/sin(q)cos(q) = adj/hypsec(q) = 1/cos(q)tan(q) = sin(q)/cos(q)cot(q) = 1/tan(q)
What does Adj stand for in trigonometry?
Introduction to Right Triangle Trigonometry Opp stands for the leg opposite of the angle \begin{align*}\theta\end{align*}, hyp stands for hypotenuse, and adj stands for the leg adjacent to the angle \begin{align*}\theta\end{align*}.
Is CSC a HYP adj?
sine(q) = opp/hypCSC(q) = 1/sin(q)COs(q) = adj/hypsec(q) = 1/COs(q)tan(q) = sin(q)/COs(q)cot(q) = 1/tan(q)How do you find HYP?
- Draw the altitude of the hypotenuse on the triangle. …
- Divide the length of the shortest side of the main triangle by the hypotenuse of the main triangle.
- Multiply the result by the length of the remaining side to get the length of the altitude.

Sine and cosecant are positive in Quadrant 2, tangent and cotangent are positive in Quadrant 3, and cosine and secant are positive in Quadrant 4.
What is the ADJ term?An adjective is a word that tells us more about a noun. It “describes” or “modifies” a noun (The big dog was hungry). In these examples, the adjective is in bold and the noun that it modifies is in italics. An adjective often comes BEFORE a noun: a green car.
Article first time published onWhat is the difference between OPP and adj?
In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle. We use special words to describe the sides of right triangles.
Is SOH CAH TOA offensive?
While SOHCAHTOA can be fun to say, as is often noted of the mnemonic, these comparisons can be very insensitive and offensive.
Is Sohcahtoa a trigonometry?
Sohcahtoa: SOHCAHTOA is a mnemonic device that is used in mathematics to remember the definitions of the three most common trigonometric functions. … Sine, cosine, and tangent are the three main functions in trigonometry. They’re all based on ratios obtained from a right triangle.
What is the Sohcahtoa rule called?
Soh…Sine = Opposite / Hypotenuse…cah…Cosine = Adjacent / Hypotenuse…toaTangent = Opposite / Adjacent
What is the HYP leg Theorem?
The HL Postulate states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.
What is the shortest side of a 30 60 90 triangle?
And so on. The side opposite the 30° angle is always the smallest, because 30 degrees is the smallest angle. The side opposite the 60° angle will be the middle length, because 60 degrees is the mid-sized degree angle in this triangle.
Is the value of tan 60 degree?
Therefore, the exact value of Tan 60 degrees is √3.
What is a Quadrantal angle?
Definition A quadrantal angle is an angle in standard position whose terminal ray lies along one of the axes. Examples of quadrantal angles include, 0, π/2 , π , and 3π/ 2. Angles coterminal with these angles are, of course, also quadrantal.
What is reference angle?
Definition of Reference Angle: Let θ be a non-quadrantal angle in standard position. The reference angle of θ is the acute angle θR that the terminal side of θ makes with the x-axis. … Always find the difference between the angle and the positive or negative x-axis.
Is CSC a sin or cosine?
The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

What is a adj example?
What is an adjective? Adjectives are words that describe the qualities or states of being of nouns: enormous, doglike, silly, yellow, fun, fast. They can also describe the quantity of nouns: many, few, millions, eleven.
What is the ADJ of create?
Explanation: adjective form of create is. (b) creative.
What is the ADJ of support?
supportable. Capable of being supported, upheld, maintained, or defended.
How do you tell if a word is a adj?
Look for a word before a noun that describes the noun. The nouns is the person, place or thing that is the subject of the sentence. Then, check to see if there is a descriptive word right before the noun. If there is, then it may be an adjective.
What is a tan in math?
The tangent of an angle is the trigonometric ratio between the adjacent side and the opposite side of a right triangle containing that angle. tangent=length of the leg opposite to the anglelength of the leg adjacent to the angle abbreviated as “tan” Example: In the triangle shown, tan(A)=68 or 34 and tan(B)=86 or 43 .
