If cos ^(-1)((3)/(5))-sin ^(-1)((4)/(5))=cos ^(-1) x, then x=

Evaluate: i) sin(cos^(-1)(3/5)) , ii) cos(tan^(-1)(3/4))

tan [sin ^(-1)((3)/(5))-cos ^(-1)(-(4)/(5))]=

cos[sin^(-1)(-4//5)-cos^(-1)(4//5)]=

If (sin^(4))/(2)+(cos^(4))/(3)=(1)/(5) then

Which of the following angles is greater ? theta_(1) = sin^(-1).(4)/(5) + sin^(-1).(1)/(3) and theta_(2) = cos^(-1).(4)/(5) + cos^(-1).(1)/(3)
