Question & Answer: Calculate: (a) cos (7 pi/9) + tan (7/15 pi) sin (15 degree) (b) sin^2 80 degree – (cos 14 degree sin 8…..

Calculate the following trig functions using Matlab code

Calculate: (a) cos (7 pi/9) + tan (7/15 pi) sin (15 degree) (b) sin^2 80 degree – (cos 14 degree sin 80 degree)^2/^3 squareroot 0.18

Expert Answer

ans = cos(7*pi/9) + tan(7*pi/15)*sind(15)

ans = sind(80)^2 – ((cosd(14)*sind(80))*(cosd(14)*sind(80))/((0.18)^(1/3)))
