Simplify :
`SinA . Sin^3(A/3 ) + CosA . Cos^3( A/3 ) `=

Find simplified form : ( SinA + CosA )^2 + ( SinA + CosA )^2 =

Show : (( Sin^3A + Cos^3A ) /( SinA + CosA ) ) = 1 - SinACosA

Simplify: (sin3A)/(sin A)+(cos3A)/(cos A)

SinA - CosA = 0 , Sin^4A + Cos^4A = ?

On simplifying (sin^3A+sin3A)/(sinA)+(cos^3A-cos3A)/(cosA) we get

(sinA + sin3A) / (cosA + cos3A) = tanalpha, (cosA-cos2A) / (sinA + sin2A) = tanbeta, (sinA + sin3A + sin5A + sin7A) / (cosA + cos3A + cos5A + cos7A) = tan gamma , (cosA-cos5A-cos9A + cos13A) / (sinA-sin5A + sin9A-sin13A) = tandelta, then (a) alpha = 4beta (b) gamma = 2alpha (c) gamma = delta (d) none

Show that : Sin^4A - Cos^4A = ( SinA + CosA ) ( SinA - CosA )

CosA/(1-SinA) + SinA/(1-CosA) + 1 =

Prove that: (sinA - 2sin^(3)A)/(2 cos^(3)A - cosA) = tan A

The simplified value of 1- (sin^(2)A)/(1+ cosA) + (1+ cosA)/(sinA) - (sinA)/(1- cosA) is:
