Simplifying trigonometric identities examples
Webb3)Use the fundamental trig identities to simplify the expression cos²y 1- sin y)cos² y= 1 - sin²y = (1-sin y)(1+sin y) = 1+sin y 1- sin y 1-sin y 4) Prove that tan x = sec x sin x First, … WebbRecall from the last section, the sine of the sum of two angles: sin (α + β) = sin α cos β + cos α sin β. We will use this to obtain the sine of a double angle. If we take the left hand side (LHS): sin (α + β) and replace β with α, we get: sin (α + β) = sin (α + α) = sin 2 α. Consider the RHS: sin α cos β + cos α sin β.
