I REALLY need help on these problems. PLEASE HELP ME!!!

6-58. Ryan thinks that sin x = 0.3 is the same as sin (0.3) = x. Is Ryan correct? What does Ryan have to take into consideration for these two expressions? 6-59. Is it true that the sine function distributes over addition? That is, is it true that sin(a + B) = sin o + sin B for all angles o and B? Justify your answer using special angles. 6-60. Find a and b such that 2x2 + 8x + a=2(x+b). 6-61. For the equation y = 3 sin ( 2 (x -2) ) + 1, find the amplitude, horizontal and vertical shifts, and the period. 5-62. Find the exact value of tan 21 . 6-63. Using APOR, find the equations for the following lines. Q(2, 12) a. The perpendicular bisector of PR. b. The median line that goes from Q to the midpoint of PR. P(-4, 6) R(14, 2) c. The altitude of APOR from Q to side PR. 6-64. Estimate A(f(x) = 1, 15 x35) using 8 midpoint rectangles. Use sigma notation to show the sum of the areas
