Solution: Evaluate (sin⁡ 0°+sin 1°+sin⁡ 2°+ ⋯. +sin⁡ 89°+sin⁡ 90°)/(cos⁡ 0°+cos⁡ 1°+cos⁡ 2°+ ⋯.+cos⁡ 89°+cos⁡ 90°)

Evaluate the following: (sin⁡ 0°+sin 1°+sin⁡ 2°+ ⋯. +sin⁡ 89°+sin⁡ 90°)/(cos⁡ 0°+cos⁡ 1°+cos⁡ 2°+ ⋯.+cos⁡ 89°+cos⁡ 90°)

Evaluate the following: (sin⁡ 0°+sin 1°+sin⁡ 2°+ ⋯. +sin⁡ 89°+sin⁡ 90°)/(cos⁡ 0°+cos⁡ 1°+cos⁡ 2°+ ⋯.+cos⁡ 89°+cos⁡ 90°)
