The importance of studying cos Theta is important because it can be used to solve Cosine problems. 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 Cotange...
sin(theta) + cos(theta) tan(theta). Write the trigonometric expression as an algebraic expression. cos(2 arctan x). Given that cos(theta) = 1/3, use one of the identities to find the exact value of sec(theta). Write the following in terms of...
Prove the identities: 1−12sin2θ=sin3θ+cos3θsinθ+cosθ Double Angle Formula The sine of a double angle for a given angle θ is the double the product of the sine and the cosine of the given angle. Thus, we can state, sin...

sin2θ+sin2θ=1 Half-angle formula for sine function: sin2θ=2sinθcosθ Answer and Explanation: We are given a trigonometric expression. We want to prove that it is an identity. Using the identities on the context section we have that: $$\begin...Be...
When verifying trigonometric identities, we usually need to show that the left-hand side of an equation is equal to the right-hand side. To do this, we can use trig definitions (such as tanx=sinxcosx) and known trig identities (such as cos2x+sin2...
\[\sin \left( {{{60}^o}} \right) = \frac{{\sqrt 3 }}{2}\] \[\operatorname{Tan} \left( \theta \right) = \frac{{Opposite}}{{Adjacent}}\] \[\tan \left( {{{60}^o}} \right) = \frac{{\sqrt 3 }}{2}\] We can calculate the values of sine, cosine and tangent with...
