Sin 90+θ is equal to

WebbWe'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 ∘. WebbIsosceles triangles have two equal side lengths and two equal angles, making them symmetric on one axis. Even though scalene triangles’ sides and angles are all different, they are still very useful when they have a right-angle. There are three tricks to remember sin, cos, and tan values for 30°, 45°, and 60°.

It is because 180° is in the second quadrant and the value of sine theta that exceeds 90° shifts to the cosine function. That is to say, Sin (90 + X) = cos X. Sin 180 can be written as: Sin 180 = Sin (90+90) = Cos 90. Since cos 90 = 0, we get. Sin 180 = 0.
