The value of `sin^(-1)(x^(2)-4x+6)+cos^(-1)(x^(2)-4x+6)` for all `x in R` is

Find the value of : 2 (sin^(6) x + cos^(6)x) - 3 (sin^(4) x + cos ^(4)x) + 2 .

Value of sin^(6)x+cos^(6)x+sin^(4)x+cos^(4)x+3+5sin^(2)x cos^(2)x is

Find the value of: 2("sin"^(6)x+cos^(6)x)-3("sin"^(4)x+cos^(4)x)+2 .

cos ^(2) 2x -cos ^(2) 6x = sin 4x sin 8x

cos ^(2) 2x -cos ^(2) 6x = sin 4x sin 8x

cos ^(2) 2x -cos ^(2) 6x = sin 4x sin 8x

cos ^(2) 2x -cos ^(2) 6x = sin 4x sin 8x

cos ^(2) 2x -cos ^(2) 6x = sin 4x sin 8x

What is the value of [(sin7x- sin5x)/ (cos 7x + cos 5x)]- [(cos 6x-cos 4x)/ (sin 6x + sin 4x)] ? [(sin7x- sin5x)/ (cos 7x + cos 5x)]- [(cos 6x-cos 4x)/ (sin 6x + sin 4x)] का मान क्या है?

Prove that, sin^(6)x + cos^(6)x = 1-3/4 sin^(2) 2x.
