Verify the identity: cot(x-pi/2)=-tan x Given sin(x) = 4/7 and cos(x) = -sqrt(33/7), how do you find cot(x)? Prove that : tanx + cotx = 2sec(2x) Prove if an identity \csc(x) - \cot(x) = \frac{\sin(x)}{1 + \cos(x)}. ...
Simplify the expression. sec^2 x - 1 / sec x - 1 If f(x) = \tan(\sqrt{x}) + \sec(x), find f'\left ( \frac{3\pi}{4} \right ). Solve. \tan(x) + 1 = \sec(x) Carefully show how to simplify (cot^2 x - csc^2 x)/(cos x) to get -sec x. ...
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...
Use the triangle below to find the values of sin θ, cos θ, tan θ, csc θ, sec θ, and cot θFirst, we need to find the length of the hypotenuse using the Pythagorean theorem. c2 = 152 + 82 c2 = 225 + 64 c2 = 289 c = √289 ...
Step 2: Use definitions to find the remaining trigonometric functions. {eq}\sin(\theta) = \frac{3}{5} {/eq} {eq}\tan(\theta) = \frac{3}{4} {/eq} {eq}\csc(\theta) = \frac{5}{3} {/eq} {eq}\sec(\theta) = \frac{5}{4} {/eq} {eq}\cot(\theta) =...
Well, time to build a ramp to the ceiling, and have a little chit chat. You pick an angle to build and work out: cotangent(x) = cot(x) = how far the ceiling extends before we connect cosecant(x) = csc(x) = how long we walk on the ramp ...
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...
Use the given value and the trigonometric identities to find the remaining trigonometric functions of the angle. \sec \theta = - \frac{4}{3}, \cot \theta is greater than 0 What is sin(x) - csc(x) simplified? Finding identity: (1) cscx - cscx co...
The number for which you want to find the remainder. divisor Required. Divisor is number by which you want to divide the number (first argument). 3. Example 1 The image above demonstrates the result the MOD function returns using different numbers in both arguments number and divisor. The ...
Remember that these relationships only apply to right triangles. You can also find the reciprocal of sine and tangent in the same manner as in the tutorial where the reciprocal of sine is cosecant (csc) and the reciprocal of tangent is cotangent (cot). See the Resources. Note that on some...
