Graph the curve x = 2 cos(theta) − cos(2theta),     y = 2 sin(theta) − sin(2theta) If this curve is rotated about the x-axis, find the area of the resulting surface. (Use your graph to help find the correct parameter interval.)

п 4. Find the slope of the tangent line to the polar curve r = 1 – sin40 at 0 = 4 : a. 3 b. 4 c. 2 d. 4 5/3 +4 1-4/3 e.

A point starts at (x, y) = (4.8, 0) and moves CCW along a circular path centered at (x, y) = (0, 0). Imagine an angle with a vertex at the center of the circular path subtending the path the point has traveled. Let 0 represent the angle's measure (in radians). Write formulas expressing the x and y- coordinates of the point in terms of 0. Preview Y = Preview Box 1: Enter your answer as an expression. Example: 3x^2+1, х/5, (а+b)/с Be sure your variables match those in the question Box 2: Enter your answer as an expression.
