Question

Find the approximate value of each trigonometric function.31Given that tano 3.454 where << ,find the values of sing and coso. If necessary, round to 32'decimal places.In Quadrant III, sino sand costs

Answer 1

cos theta = -0.278

sin theta = -0.961

Step-by-step explanation:

Given the expression

tan theta = 3.454

Get the value of thets

theta = arctan 3.454

theta = 73.85degrees

since theta is between 90 and 270 and lies in the third quadrant, then;

theta = 180+73.85

Get cos theta and sin theta

cos theta

= cos 253.85

= -0.278

sin theta

= sin 253.85

= -0.961

Hence cos theta and sin theta are -0.278 and -0.961 respectively
