Calculus: Early Transcendentals 8th Edition

$sin\theta=-\frac{3}{4}$ $cos\theta=\frac{\sqrt 7}{4}$ $tan\theta=-\frac{3}{ \sqrt 7}=-\frac{3\sqrt 7}{ 7}$ $sec \theta=\frac{4}{\sqrt 7}=\frac{4\sqrt 7}{ 7}$ $cot\theta=-\frac{\sqrt 7}{ 3}$
Since $csc\theta=-\frac{4}{3}$, we can label the hypotenuse side as having length 4 and the opposite side as having length 3. The Pythagorean Theorem gives adjacent side $=\sqrt {4^{2}-3^{2}}=\sqrt 7$ The other five trigonometric functions are given as follows: $sin\theta=-\frac{3}{4}$ $cos\theta=\frac{\sqrt 7}{4}$ $tan\theta=-\frac{3}{ \sqrt 7}=-\frac{3\sqrt 7}{ 7}$ $sec \theta=\frac{4}{\sqrt 7}=\frac{4\sqrt 7}{ 7}$ $cot\theta=-\frac{\sqrt 7}{ 3}$
