Cos theta + 90
WebThe bottom triangle is a right triangle with hypotenuse length h = cos phi. So if x were your unknown side, doing normal trig on it gives cos theta = x/h = x / (cos phi), or in other words x = (cos theta)(cos phi). All of the sides in that diagram are defined in the same way, … WebLösen Sie Ihre Matheprobleme mit unserem kostenlosen Matheproblemlöser, der Sie Schritt für Schritt durch die Lösungen führt.

WebWe've shown that \sin (\theta) = \cos (90^\circ-\theta) sin(θ) = cos(90∘ −θ). In other words, the sine of an angle equals the cosine of its complement. Well, technically we've only shown this for angles between 0 ^\circ ∘ and 90 ^\circ ∘.
