41&43 In Problems 41-46, use the given information and appropriate identities to find the exact value of the indicated expression. 41. Find sin(x + y) if sin x = 1/3, cos y = -3/4, x is in quadrant II, and y is in quadrant III. 42. Find sin(x - y) if sin x = -2/5, sin y = 2/3, x is in quadrant IV, and y is in quadrant I. 43. Find cos(x - y) if tan x = -1/4,...
May you show some steps? I am completely clueless on how to solve these type of questions. Thank you! exact Find the value of cos(x + y). Given sin x = žand cos y = 5, x is an angle in Quadrant II and y is an angle in Quadrant I
please show work :) 3. Solve logzx + log2(x+6)=4 4. Given sine -- and cos se and in quadrant IV, sond) sin(x+B). (b) tanla+B). (c) the quadrant of the angle (a +).
please if you put these in radian deimal form that would help me understand this please Question 3 1 pts Given A in quadrant I, with sin A=4/15, and B in Quadrant 1, with tangent B=16/7 find cosine of A+B Question 4 1 pts Given e arcsin (2/19) find cos cos( ) je
I know the limit is only question per post, so if you could please just help me out with number 25! I havent done this in awhile and I need my memory refreshed with how to do these problems. Thank you! Solve, finding all solutions in [0,271). 25. 4= 4 sin’ x+3 26. cos” x = 2 cos x 27. 1–3 tan” x = 0
From the information given, find the quadrant in which the terminal point determined by t lies.

please answer 1,2 and 3! 1. 2. 3. Verify that the equation is an identity. (Hint: sin 2x = sin (x + x)) sin 2x = 2 sin x cOS X Substitute 2x = x + x and apply the sine of a sum identity. sin 2x = sin (x + x) (Do not simplify.) Use the given information to find (a) sin (s +t), (b) tan (s+t), and (c) the quadrant of s + t. 3 12 and sint=...
