we will start with the left-hand side (LHS) and manipulate it step by step to reach the right-hand side (RHS). Step 1: Apply the sine addition and subtraction identitiesWe use the identities for the sum and difference of sines:- sinA+sinB=2sin(A+B2)cos(A−B2)- sinA−sinB=2sin...
Perform the addition or subtraction of the following and use the fundamental identities to simplify the expression: \dfrac{1}{1 + cos(x)} + \dfrac{1}{1-cos(x)}. Use the fundamental identities to fully simplify the expression. \tan x \sin x + \sec x \cos^2x Write cos(4x) cos(x...
