If {eq}\cos(\theta)=\dfrac{8}{17} {/eq} and {eq}\sin(\theta)<0 {/eq}, find the exact value of {eq}\tan(\theta) {/eq}. Finding the Value of the Tangent Function: Generally, the tangent function is equivalent to the sine function over the cosine function. $$\t...
Obviously some values of tan are needed, but since they are not directly on the table they need to be computed: tan45=1 is easy, whiletan41.25≃sin41.25cos41.25≃sin41.25sin48.75≃0.65930.7518≃0.8770. So taking θ=41.25 you get that the required...
The Pythagorean identity is the identity that originated from the Pythagorean theorem. It states the addition of the sine squared function and cosine squared function results in a numerical value one. The identity is as follows: $$\sin^2 \theta + \cos^2 ...
