Find the exact value of the six trigonometric functions of the angle $胃$ in each figure.

Short Answer

Expert verified

Required values of the six trigonometric functions are:

$\sin 胃 = \frac{b}{c} = \frac{\sqrt{2}}{\sqrt{3}} \cos 胃 = \frac{a}{c} = \frac{1}{\sqrt{3}} \tan 胃 = \frac{b}{a} = \frac{\sqrt{2}}{1} = \sqrt{2} c s c 胃 = \frac{c}{b} = \frac{\sqrt{3}}{\sqrt{2}} s e c 胃 = \frac{c}{a} = \frac{\sqrt{3}}{1} = \sqrt{3} c o t 胃 = \frac{a}{b} = \frac{1}{\sqrt{2}}$

Step by step solution

Step 1. Given information

Let us consider the hypotenuse as 'c' , opposite as 'b' and the adjacent as 'a' .

Pythagorean Theorem:

$c^{2} = a^{2} + b^{2}$ , where a, b and c are adjacent, opposite and hypotenuse respectively.

Trigonometric Functions:

$\sin 胃 = \frac{b}{c} c s c 胃 = \frac{c}{b} \cos 胃 = \frac{a}{c} s e c 胃 = \frac{c}{a} \tan 胃 = \frac{b}{a} c o t 胃 = \frac{a}{b}$

Step 2. Calculation

$G i v e n, b = \sqrt{2}, a = 1 B y P y t h a g o r e a n t h e o r e m, c^{2} = b^{2} + a^{2} = {(\sqrt{2})}^{2} + 1^{2} = 2 + 1 = 3 c = \sqrt{3} n o w, \sin 胃 = \frac{b}{c} = \frac{\sqrt{2}}{\sqrt{3}} \cos 胃 = \frac{a}{c} = \frac{1}{\sqrt{3}} \tan 胃 = \frac{b}{a} = \frac{\sqrt{2}}{1} = \sqrt{2} c s c 胃 = \frac{c}{b} = \frac{\sqrt{3}}{\sqrt{2}} s e c 胃 = \frac{c}{a} = \frac{\sqrt{3}}{1} = \sqrt{3} c o t 胃 = \frac{a}{b} = \frac{1}{\sqrt{2}}$
