Q2 20 Find all solutions of the equati tanx=13 125 Find all solutions of the equat tanx=1 Find all solution of the equabon C)x= VE 123 Find all solutions of the equation 13 (22) use substitution to de berminé whether the given X value is a solution of the equation sinx_ ve x = 7 sin Xzi

Answer 1

26. tan x = - N3 is Х. = tant NB) ot 1 a The exact value of tant (de) is Inayo washiro no Wriolimine The tangent function in positive first and third quadrants To find the second reference angle from & to find the solution in the fourth quadrant in the solution, add X = a + 4A The function is هل period of the taux values will repeat every both direction: [no integer radians X in T + nt etroasa

x 24- 6 6 2x so radians The period of the cost fanction in values will repeat every in both direction for. 11K T 6 + 2an + aan D [x = integer Locosm 23: Sina a NO 2 Sin-1 (A) x ? id T 3. ا و ا ا ر The exact value of Sin ($½ is , 3 The sine in the function in positive first and second quadrants. To find the second solution, subtract the reference angle from find the solution in the second quadrant. t to

x = *- A 27 Son Values The period of the sin com ferination will repeat every at radiam in both direction. The general solution - Pracolo VA 2 +2th ; +2an 2 3 ina integer Griven, & 6 Now, substitute x2 in the given & equations ton et 22 Sint = 2. sin Griz 1 # all solo 2 2. So is not a solution of the equation GYO
