Find all solutions to the equation. cos^2x + 2 cos x + 1 = 0?3. Find all the solutions of each of the following equations in the given range (a) cos2x = 1 √ 2 for −180o< x < 180o (b) tan3x = 1 for −90o< x < 90o (c) sin2x = 1 2 for −180o< x < 0 (d) cos 1 2 x = − √ 3 2 for −180o< x < 180o 4. Using identities in the solution of equations There are many trigonometricidentities. Two commonlySolve for x cos(x)^2-cos(2x)=0. Replace the with based on the identity. Reorder the The complete solution is the set of all solutions., for any integer, for any Since the radical is on the right side of the equation, switch the sides so it is on the left side of the equation. To remove the radical on the left side of the equationFind an equation for the line that passes through the point (2, −5) and is parallel to the line 2x − 4y = 5.? is tangent to circle A at point G.
