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).
The Cos Theta Formula is a Mathematical formula used to calculate the Cosine of an angle. It can be abbreviated as Cos(θ) and looks like this: Cos(θ) = adjacent/hypotenuse. In other words, it takes the length of the adjacent side (the side next to the angle) and divides it by th...
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...

Half-angle formula for sine function: {eq}\sin 2\theta=2\sin \theta\cos \theta {/eq} Answer and Explanation:1 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: ...
\[\sin \left( {{{60}^o}} \right) = \frac{{\sqrt 3 }}{2}\] \[\operatorname{Tan} \left( \theta \right) = \frac{{Opposite}}{{Adjacent}}\] \[\tan \left( {{{60}^o}} \right) = \frac{{\sqrt 3 }}{2}\] We can calculate the values of sine, cosine and tangent with...
