4-dsin2x-3=O Part I: Rewrite this equation so that it is expressed in terms of 5m? X = a, where a is a nonzero number. (2 points) Part II: Solve this equation for sinx by taking the square root of both sides. Be sure to include all possible values that satisfy the equation. (2 points) Part III: Solve each equation separately to get the full solution set, choosing only solutions on the interval [0.22]. (4 points) 5. cos(3x) = -1 Part I: Using an appropriate inverse trigonometric expression, write an equation that defines the value of 3x. (2 points) Part II: Solve this equation to find all possible values of the angle 3x. (4 points)Part III: Use algebra to find all values of x between 0 and 2n that satisfy this equation. (4 points)
