WebMay 5, 2011 · You should look into ChebyshevT polynomials. It has the property that ChebyshevT [3, Cos [th] ]==Cos [3*th]. So for your problem the answer is In [236]:= x/2 + ChebyshevT [3, x/2] Out [236]= -x + x^3/2 Alternatively, you could use TrigExpand: Web Step 1: Identify the given trigonometric expression. cot(θ) csc(θ) cot ( θ) csc ( θ) Step 2: Simplify the expressions using trigonometric identities.
7.1: Simplifying Trigonometric Expressions with Identities
WebYou would need an expression to work with. For example: Given sinα = 3 5 and cosα = − 4 5, you could find sin2α by using the double angle identity. sin2α = 2sinαcosα. sin2α = 2(3 5)( − 4 5) = − 24 25. You could find cos2α by using any of: cos2α = cos2α −sin2α. cos2α = 1 −2sin2α. cos2α = 2cos2α − 1.
