88 degrees, using the central angle and inscribed angle theorems, the central angle, in this case MON, equals the central arc. The inscribed angle is half of the arc, in this case the central arc. So MLN is half of MON.

Find an equation of the plane tangent to the following surface at the given point.z equals tangent Superscript negative 1 Baseli

Sergeeva-Olga [200]

Let f(x, y, z) = z - arctan(x y). Compute the gradient of f at the point (0, 3, 0):

∇ f(x, y, z) = (-y / (1 + x²y²), -x / (1 + x²y²), 1)

∇ f (0, 3, 0) = (-3, 0, 1)

This vector is orthogonal to the surface z = f(x, y). Then the equation of the tangent plane is

∇ f (0, 3, 0) • (x, y - 3, z) = 0

(-3, 0, 1) • (x, y - 3, z) = 0

-3x + z = 0

z = 3x
