therefore, sin 90 degree equals to the fractional value of 1/ 1. sin 90° = 1 the most common trigonometric sine functions are sin 90 degree plus theta \(\begin{array}{l}\sin (90^{\circ}+\theta )=\cos \theta\end{array} \) sin 90 degree minus theta \(\begin{array}{l}\sin...
Verify the identity. sin x plus or minus sin y / cos x + cos y = tan x plus or minus y / 2 Prove that the both sides of the trigonometric identity are equivalent. {cos (x + y)} / {cos x cos y} = 1 - tan x tan y. ...
Determine whether the statement is true or false. sin(u plus or minus v) = sin u cos v plus or minus cos u sin v Determine whether the statement is true or false. If it is true, explain why. If it is false, explain why or give an exa...
1+sec(-x)/ sin (-x) + tan (-x) = - csc x Verify that the equation is an identity. {cos 2 x} / {cos x} = cos x - sin x tan x Verify the identity. Write 4 cos 2theta sin 4theta as a sum or difference. Verify the identity. sin x plus...
