In addition, Cosine forms part of the SOHCAHTOA Formula which will help you find all six trigonometric functions (Sine, Cosine, Tangent, Vertical Angle/Cosecant, Oblique Angle/Secant, and Cotangent) from one angle. This makes Cos Theta a valuable tool when working with other Trigonometry Formu...
Find the angle \theta between the vectors v=2\vec i+\vec k, w=\vec j-3\vec k. Find the angle \theta between two vectors v= -\sqrt{\frac{3}{2i - \sqrt{\frac{3}{2j\ and\ w= 4\sqrt{3} i + 4j. Find the angle theta between the...
Cos Theta Formula Questions Example 1: If Sin x = 4/5, Find the value of Cos x? Solution: Using Trigonometric identities: Cos2x = 1- Sin2x Cos2x = 1 – (4/5)2 = 1 – 16/25 = (25 – 16) / 25 = 9/25 Cos x =
