How to Find Exact Values of Sine & Cosecant Using the Unit Circle & Special Triangles: Example with Sine Evaluate the expressionsin225∘. Give an exact answer. Step 1:225∘is in quadrant III since180∘<225∘<270∘. Therefore,sin225∘is negative. ...
Find the cosecant of the product for both triangles, this number will be the length of the dividing line that forms the hypotenuse. The cosecant is often found on calculators as either "csc", "asin", or "sin^-1". For example the cosecant of 0.15 would be 8.63 (csc15 = 8.63). St...
How to findcos4π7? Question: cos4π7 Trigonometric Identities: Trigonometry is an important concept in mathematics. The six types of trigonometric functions are sine, cosine, tangent, cosecant, secant and cotangent. Each trigonometric function is related to other. ...
How to Find Trigonometric Ratios Given a Right Triangle Step 1: Identify the hypotenuse (hyp), adjacent (adj), and opposite (opp) sides of the given right triangle relative to the indicated acute angle. Step 2: Using the following formulas, calculate the trigonometric ratios: $$\begin{ali...
Sign: The "primary" functions are positive, and the "co" (complementary) functions are negative Scale: The hypotenuse (red) used by each function Swap: The other function in each Pythagorean triangle (sin ⇄ cos, tan ⇄ sec, cot ⇄ csc) Derivative: Multiply to find the derivativeTada...

To find the inverse of a function of x, substitute y for x and x for y in the function, then solve for x.
These ratios can also be considered to be the basic trigonometric ratios. Apart from these three, there are some other trigonometric ratios as well that are somewhat related to the basic ratios. The other three ratios are cosecant, secant, and cotangent. The product of these ratios and the ...
Looking at our trig cheatsheet, we find an easy ratio where we can compare secant to 1. For example, secant to 1 (hypotenuse to horizontal) is the same as 1 to cosine: Suppose our secant is 3.5, i.e. 350% of the radius of the unit circle. What’s the angle to the wall?
The CSC function calculates the cosecant of an angle (radians). It returns the same value as 1/SIN(number) which is the reciprocal of the sine function. 1. Introduction What is the cosecant? The cosecant is one of the trigonometric functions closely related to the sine function. The co...
