If we make larger the area of the sine function to the set of complicated numbers, then letting theta= a+bi, the place a and b are the two genuine, and that i is the imaginary unit. sin(a+bi)=2 sin(a)cos(bi)+sin(bi)cos(a)=2 (sum of angles id for sin(x)) utilising hyperbolic indentities, we get. sin(a)cosh(b)-i*sinh(b)cos(a)=2

Hello
θ +(2θ + 30°) = 90°
3θ = 90-30° = 60°
θ = 20°
sin(20) = 0,34202
cos (70) = 0,34202
sin(x) = cos(90-x)
