Hello all,

i am doing some project right now , but i have a small problem calculating some expressions like this :

cos(i) = cos(32) × sin(86)

so i = 32.223^{o}

I cant understand how is this i calculated . I have stuck due to this , i know its probably something really small that i should probably know, but i am stuck now like my mind gave up -.- .

Any help is very welcome.

Those numbers (32 and 86 as well as the result i=32.223 are all in degrees)
