Plot the complex number in the complex plane.2i

Find the angle between v and w. Round your answer to one decimal place, if necessary.v = 5i,w = j

Solve the problem.Find a vector v whose magnitude is 20 and whose component in the i direction is five times the component in the j direction.

The letters r and θ represent polar coordinates. Write the equation using rectangular coordinates (x, y).r = cos θ

Test the equation for symmetry with respect to the given axis, line, or pole.r = -4 cos θ; the polar axis

The letters x and y represent rectangular coordinates. Write the equation using polar coordinates (r, θ).y2 = 16x

Use the figure below. Determine whether the given statement is true or false. C + D + G + I + J = 0

Decompose v into two vectors v1 and v2, where v1 is parallel to w and v2 is orthogonal to w.v = i + 7j,w = i + j
