If `sinx=A`, find `cos2x` in terms of A.

Let A=sinx+cosxdot Then find the value of sin^4x+cos^4x in terms of Adot

Let A=sinx+cosxdot Then find the value of sin^4x+cos^4x in terms of Adot

Let A=sinx+cosxdot Then find the value of sin^4x+cos^4x in terms of Adot

Let y=tan ^(-1)((1-cos x)/(sin x)) i) Express 1-cos x and sinx in terms of sin (x/2) and cos (x/2) ii) Hence find (dy/dx) .

If sinx =2/3 , then find the value of cos3x . यदि sinx =2/3 ,तो cos3x का मान ज्ञात कीजिए।

If the determinant |(cos2x, sin^2x,cos4x),(sin^2x , cos2x,cos^2x),(cos4x,cos^2x,cos2x)| is expanded in powers of sinx , then the constant term in the expansion is :

If cos^2 x +7sinx=5 ,find values of sinx.

(sin3x-sinx)/(cos2x) =

If A=[(cosx,sinx),(-sinx,cosx)] , show that A^(2)=[(cos2x,sin2x),(-sin2x,cos2x)] and A^(1)A=1 .

sinx + cosx = sqrt(2) cos2x
