Question 1 6 pts 3 Given: tan and sin 0 <0. Find sec A. - B. con le C. D.
If tan = TT TT << 2 2 then sin =
2 If tan 0 = 3,00< 2 o<5, find sin 0 2 sin =0 (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.)
19. If the cos u= -5/13 where it <u<37 12 and sin v= 8/15 where tan v<0, find sin (u+v)
The answers for part b are sin(A/2) = √26/26, cos(A/2) = -5√26/26, and tan(A/2) = -1/5, but I can't figure out how to get there lies and (b) find the 24. Iftan A = with 34 < A< 21, then (a) determine the quadrant in which exact value of sin (), cos (), and tan ().
Suppose sin(a)= - 3 5 with 180°<a <270°, what is cos(2a)? 24 25 7 25 7 O 24 24 O 25
el 37-40 Quadrant in which an Angle Lies Find the quadrant in which 0 lies from the information given. 37. sin 0 <0 and cos e o ( 38. tan <0 and sine < 0
Use the information given about the angle 8 to find the exact value of each trigonometric function tan = - 10, sin < 0 0 e e (a) sin (20) (b) cos (20) 2 (d) cos 2 (e) tan 20 (f) tan 2 (c) sin
Using the identity sin? 0 + cos² 0 = 1, find the value of tan 6, to the nearest hundredth, if sin 0 = -0.62 and 3 < 0 < 27.
