sin[(1)/(2)cos^(-1)(4)/(5)]

Evaluate sin(1/2cos^(-1)(4/5))

Find the value of sin(tan^(-1)((1)/(2))-cos^(-1)((4)/(5)))

sin(cos^(-1)(4/5))

Prove that: sin^(-1)((5)/(13))+cos^(-1)((4)/(5))=(1)/(2)sin^(-1)((3696)/(4225))

Prove that : sin^(-1)(5/13)+cos^(-1)(4/5)=1/2sin^(-1)(3696/4225) .

Evaluate: i) sin{pi/3-sin^(-1)(-1/2)} ii) sin(1/2cos^(-1)4/5) iii) sin(cot^(-1)x) iv) tan1/2(cos^(-1)sqrt(5)/3)

Evaluate cos(sin^(-1)(4/5)+cos^(-1)(2/3))

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

cos[2cos^(-1)((1)/(5))+sin^(-1)((1)/(5))] =
