Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.

tan-1(0.4877) = 25.99849161 or about 26 degrees

The angle between the radius and the tangent is a right angle of 90 degrees.

Circle equation: 2x^2 +2y^2 -8x -5y -1 = 0 Divide all terms by 2: x^2 +y^2 -4x -2.5y -0.5 = 0 Completing the squares: (x-2)^2 +(y-1.25)^2 = 6.0625 Center of circle: (2, 1.25) Point of contact: (1, -1) Slope of radius: 9/4 Slope of tangent line: -4/9 Tangent equation: y--1 = -4/9(x-1) => 9y = -4x -5 Tangent line equation in its general form: 4x+9y+5 = 0

The tangent of an angle is a ratio so, if you mean pi, and not pie, then it is simply a product of two ratios.

The angle you seek is 45 degrees. The angle whose tangent is 1 can be written arctan(1) = 45 degrees.

The reciprocal of the tangent is the cotangent, or cot. We might write 1/tan = cot.
