Sin^1 (x) cos^1 (x) = pi/2 Let sin^1 (x) = a ==> sin (a) = x Let cos^1 (x) = b ==> cos (b) = x Then we conclude that sin (a) = cos (b) We need to prove that a b= pi/2 We will use the0687basictrigonometricfunctionspdf Free download as PDF File (pdf), Text File (txt) or read online for free(12) π 2 Huo 2πsin 1(3 4) Huo π sin 1(3 4)Ti 示原方程式⇒2(1sin 2x)sin x1=0 ⇒4sin2xsin x3=0 ⇒sin x=1 Huo 3 4⇒因為0≤x≤2π Suo 以x= π 2或2πsin 1(3 4) Huo π sin1( 3 4) (13)62 4Ti 示(a)令sin 1x=θ,欲 Zhu 明cos1x=π 2θ⇔cos( π 2θ)=x ~3511~
