Calculate the sine value for one angle by dividing opposite side by adjacent side. Step 4 Find the quotient of sin(a)/A, and set it equal to x/B, where x is sin(b). Multiply both sides of the equation by B tosolve for x. ...
My goal is to calculate ∫2π0sin2k(1+a2+2acosk)1+b2+2bcosk−−−−−−−−−−−−−√dk,∫02πsin2k(1+a2+2acosk)1+b2+2bcoskdk, where a≠ba≠b and b≠1b≠1. But we may simplify it into ∫2π0sin2k(1+acosk)1+bcos...
sin(theta) = y/r = 3/5 cos(theta) = x/r = 4/5 tan(theta) = y/x = 3/4 So theta = arcsin(3/5) = arccos(4/5) = arctan(3/4) = 36.87°. This allows us to calculate the other non-right angle as well, because this must be 180-90-36.87 = 53.13°. This is because ...
