We know that tan 90° is undefined. If we try to find tan 90° on a calculator, we get an error message. To begin to get an idea of why this happens, we can use a calculator to find the tangent of angles close to 90°. Use a calculator to find tanθ, if θ takes on values of 85°, 87°, 89°, 89.9°, and 89.99°.
