WebInverse cosine is the inverse of the basic cosine function. In the cosine function, the value of angle θ is taken to give the ratio adjacent/hypotenuse. However, the inverse cosine function takes the ratio adjacent/hypotenuse and gives angle θ . cos -1 (adjacent/hypotenuse) = θ Inverse cosine symbol WebJan 31, 2014 · Set E = e π / 180 ≈ 1.01761 on the calculator. Now, E i x = cos ( x ∘) + i sin ( x ∘). You can store the conversion factor between degrees and radians as a variable and just insert it into the exponent in polar. So I stored (pi/180) in the variable R.
