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

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

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

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

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

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)

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

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

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