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

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

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

If alpha+beta=(pi)/(4) then value of (1=tanalpha).(1+tanbeta) is

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

tan2alpha-tanalpha(1+sec2alpha)=

If alpha+beta=(pi)/(4) , then the value of (1+tanalpha)(1+tanbeta) is

If sinalpha+sinbeta=1/2 , cosalpha+cosbeta=5/4 find the value of tanalpha+tanbeta

Find the adjoint of the following matrices: [(cosalpha,sinalpha),(sinalpha,cosalpha)] (ii) [(1,tanalpha//2),(-tanalpha//2, 1)] Verify that (a d j\ A)A=|A|I=A(a d j\ A) for the above matrices.

If sin alpha=(12)/(13), cos beta =4/5 and alpha, beta are two acute angles, then Value of (tanalpha-tan beta)/(1+tanalpha tan beta) is

If alpha+beta=45^(@) , show that : (1+tanalpha)(1+tanbeta)=2. Hence, find the value of tan(22(1^(@))/(2)) .
