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. WebSince the cosine function is a periodic function, we can represent cos 45° as, cos 45 degrees = cos (45° + n × 360°), n ∈ Z. ⇒ cos 45° = cos 405° = cos 765°, and so on. …
