We can get the cos 90 degrees value using the quadrant angle. Since the cos(θ) = x / r then cos(90) = 0 / 1 = 0. Attachments graph.gif 4.2 kb · views: Web why is cos(90)=0? There is no triangle, no theta exists there in the unit circle. Web definition of cos(90∘ −x) ( side adjacent to angle (90∘ − x))/( hypotenuse) but ( side opposite angle x) = ( side adjacent to angle (90∘ − x) therefore sin(x) = cos(90∘ − x) similarly cos(x) = sin(90∘ − x) answer link mason m feb 7, 2016 these can also be proven using the sine and cosine angle subtraction formulas: This is only possible (only hypothetically) when the side opposite to x equals the hypotenuse and therefore the adjacent side becomes zero in length. Oddly nothing that effects the calculation it self adds this behavior but simply the position of where i'm about to stay. Web therefore, cos(0) = 1. Web so i made this test code, which i can predict what the answer is to find out why.

Oddly nothing that effects the calculation it self adds this behavior but simply the position of where i'm about to stay. Web why is cos(90)=0? Consider a series of triangles with the base angle gradually approaching the value 0. 2,761 jan 29, 2005 #4 thank you Web therefore, cos(0) = 1. There is no triangle, no theta exists there in the unit circle. Sin x is the y value itself and cos x is the x value itself. At 0 degrees, the angle intercepts the unit circle at the coordinate (1,0). Web so i made this test code, which i can predict what the answer is to find out why. Also, look at the cosine graph.notice at pi/2 that the curve crosses the x axis at that point, i.e., the value of the cosine at that point = 0 Since the cos(θ) = x / r then cos(90) = 0 / 1 = 0.
