Find the amplitude of `sinalpha+i(1-cosalpha)`

The amplitude of the complex number z = sinalpha+i(1-cosalpha) is

If 0^(@)ltalphalt90^(@) , then solve the equation (sinalpha)/(1-cosalpha)+(sinalpha)/(1+cosalpha)=4 .

If tantheta=(sinalpha-cosalpha)/(sinalpha+cosalpha) , then sinalpha+cosalpha and sinalpha-cosalpha is equal to

If (2sinalpha)/(1+cosalpha+sinalpha)=x then find (1-cosalpha+sinalpha)/(1+sinalpha)

If tantheta=(sinalpha-cosalpha)/(sinalpha+cosalpha) , then sinalpha+cosalphaandsinalpha-cosalpha are equal to

Find |A| if A=[{:(0,sinalpha,cosalpha),(sinalpha,0,sinbeta),(cosalpha,-sinbeta,0):}]

If (2sinalpha)/(1+cosalpha +sinalpha)=y , then prove that (1-cosalpha+sinalpha )/(1+sinalpha) is also equal to y.

If (2sinalpha)/(1+cosalpha +sinalpha)=y , then prove that (1-cosalpha+sinalpha )/(1+sinalpha) is also equal to y.

Find the inverse of [(1, 0, 0),( 0,cosalpha,sinalpha),(0,sinalpha,-cosalpha)]

Givent that pi/2 lt alphaltpi then the expression sqrt((1-sinalpha)/(1+sinalpha))+sqrt((1+sinalpha)/(1-sinalpha)) (A) 1/(cosalpha) (B) - 2/(cosalpha) (C) 2/(cosalpha) (D) does not exist
