Tan 360° represents a full rotation around the unit circle. Tangent function relates opposite to adjacent sides in right triangles
Trigonometry studies angles and lengths of right triangles. Sine, cosine and tangent are primary trigonometric ratios. Tan(15°) equals tan(45° - 30°)
Tangent function is ratio of opposite to adjacent side in right triangle. Tan45° equals 1 in both fraction and decimal form. Tan45° is irrational since 45 is a nonzero rational number
The value of tan 3pi/4 is -1. Tan 3pi/4 equals tan(135°) in degrees. Tan(-3pi/4) equals -tan(3pi/4)
Tan 0 degrees equals zero in trigonometry. Tangent function is one of six main trigonometric functions. Tan 0 is defined as ratio of sin 0 to cos 0
Multiply both numerator and denominator by 3. Apply distributive property to simplify. Cancel common factor of 3
