Students can find the detailed explanation below. Cos 120°: ValueIn order to find the value of cos 120°, students need to draw a right-angled triangle (refer to the image below) and can use either of the two formulas i.e, cos (180° –θ) = – cosθ or cos (90° + θ) =...
How do you find the value for sin 2 θ , cos 2 θ , and tan 2 θ given sin θ = (3/8) and θ is in quadrant I?
we can find the sine of (45° + 30°) to give sine of 75 degrees. We now find the sine of 36°, by first finding the cos of 36°. cos 36°:The cosine of 36 degrees can be calculated by using a pentagon. Seecos36° at CutTheKnotwhere it is shown that ...

A unit vector in physics is an object that has a magnitude of 1. They are used to represent a direction. How do you write unit vectors? Any vector has a corresponding unit vector. The unit vector can be written as the vector divided by its magnitude. How do you find the unit vector...
hypotenuse but the third side is unknown i.e adjacent side. we need to find this side to find the value of cos 30 degrees. we will use the pythagorean theorem to find the value of this third side in triangle aob, ao 2 = ab 2 + ab 2 hypotenuse = d opposite side = d/2 d 2 ...
