If `cosalpha=3/5,`then value of `(sinalpha-1/tanalpha)/(2tanalpha)` is

If tanalpha=2 , then the value of (sinalpha)/(sin^(3)alpha+cos^(3)alpha) is

If secalpha=5/4 , evaluate (1-tanalpha)/(1+tanalpha) .

If sinalpha=5/13 what is the value of tanalpha+secalpha

int(tanx+tanalpha)/(tanx-tanalpha)dx

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.

If secalpha=5/4 , verify that (tanalpha)/(1+tan^2alpha)=(sinalpha)/(secalpha)

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

(a+2)sinalpha(2a-1)cosalpha=(2a+1)if tanalpha is
