(1) Find all EXACT solutions of the equationin the interval [0,2). If there is more than one answer, enter them in a list separated by commas. Enter an exact expression; decimal approximations or symbolic trigonometric expressions such as arctan(5) will be marked incorrect.

cos(x)= -sqrt of 2/2

(2)Find all EXACT solutions of the equationin the interval [0,). If there is more than one answer, enter them in a list separated by commas. Enter an exact expression; decimal approximations or symbolic trigonometric expressions such as arctan(5) will be marked incorrect.

sin (3x)= -sqrt of 3/2

(3)Find the EXACT solutions of the given equation in the interval [0,2). If there is more than one answer, enter them in a list separated by commas. Decimal approximations and symbolic trigonometric expressions such as arctan(5) will be marked incorrect. Find the symbolin the CalcPad or type pi.

6cos²(x) + 5cos(x)4 = 0

(4)Find the solutions of the equation that are in the interval [0, 2). (Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.)
