If `alpha=cos^(-1)((3)/(5)),beta=tan^(-1)((1)/(3))`, where `0ltalpha,betalt(pi)/(2)`, then `alpha-beta` is equa to :

If alpha=cos^(-1)((3)/(5)),beta=tan^(-1)((1)/(3)), where 0

If alpha = cos^(-1)((3)/(5)), beta = tan ^(-1)((1)/(3)) , where 0 lt alpha, beta lt (pi)/(2) , then alpha - beta is equal to

If alpha=sin^(-1)(2/3)" and "beta=tan^(-1)(1/2) , where 0lt alpha,betalt(pi)/(2), then find the value of alpha-beta .

If tan alpha=(1)/(7) and sin beta=(1)/(sqrt(10)), where 0

If cos(alpha+beta)=(4)/(5),sin(alpha-beta)=(5)/(13),0ltalpha,betalt(pi)/(4) then tan2alpha = …………

If alpha=tan^(-1)(tan(5 pi)/(4)) and beta=tan^(-1)(-tan(2 pi)/(3)), then 4 alpha=3 beta(b)3 alpha=4 beta(c)alpha-beta=74 alpha=(3 beta)/(12) none of these

If cosalpha=(3)/(5),cosbeta=(5)/(13),0ltalpha,betalt(pi)/(2) then find the value of sin^(2)((alpha-beta)/(2))andcos^(2)((alpha-beta)/(2)) .

If sin(alpha+beta)=1,sin(alpha-beta)=(1)/(2) where alpha,beta in[0,(pi)/(2)], then tan(alpha+2 beta)tan(2 alpha+beta) is equal to

" If cos(alpha+beta)=(3)/(5) sin(alpha-beta)=(5)/(13) and 0< alpha, beta < (pi)/(4) then tan(2 alpha) is equal to
