Find the value of the trigonometric function. If possible, give the exact value; otherwise, use a calculator to find an approximate value correct to five decimal places. (1)Please complete the following questions. ①sin (3 π )4 ②cos (3 π )4 (2)Please complete the following questions....
How do you find the exact value of a trigonometric function? For special angles (30, 45, and 60), use the side ratios shown in Figure 3 and the trigonometric functions: sin = opp/hyp, cos = adj/hyp, tan = opp/adj, csc = hyp/opp, sec = hyp/adj, and cot = adj/opp. Hyp is...
Do not use the cal- culator function keys marked sinϪ1, cosϪ1, or tanϪ1 for this purpose—these keys are used to evaluate the inverse trigonometric functions of Section 6-6, not reciprocals. S E C T I O N 6–2 Right Triangle Trigonometry 545 EXAMPLE (a) 1 Calculator ...

Find the EXACT values of the given trigonometric functions without using a calculator: (a) sin^{-1}(sin(5pi)) (b) cos(cos^{-1}(0.8)) Find the six exact trigonometric function values without using a calculator A. 150^o B. 420^o Find the exact value of ...
The first function we will define is the tangent. The tangent of an angle is the ratio of the y-value to the x-value of the corresponding point on the unit circle. In Figure 1, the tangent of angle tt is equal to yx,x≠0yx,x≠0. Because the y-value is equal to the sine of...
Question: Find the exact values of the six trigonometric functions for the following angle: {eq}\sin 30^{\circ} {/eq}. Trigonometric Function: The values of sine, cosine, and tangent of a usual angle are found in the unit circle. For the value of {eq}\di...
Find the exact values indicated. What this means is don't use your calculator to find the value (which will normally be a decimal approximation). Keep everything in terms of surds (square roots). You will need to use Pythagoras' Theorem....
Value B. Find the exact value of Because the terminal side of lies in Quadrant I, the reference angle is The cotangent function is positive in Quadrant I. Use a Reference Angle to Find a Trigonometric Value Answer: A. Find the exact value of sin 120°. ...
