What to Focus On
- Positive angles are measured anti-clockwise, negative angles clockwise
- One complete revolution = 360° = 2π radians
- Radian measure is more natural for calculus and advanced mathematics
- sin and cos have range [-1,1], others can take any real value or subset
- tan and cot are undefined when denominator is zero
- sec and cosec have range |y| ≥ 1
- Allied angles help in simplifying complex trigonometric expressions
- Function changes occur for angles of form π/2 ± θ and 3π/2 ± θ
- Sign depends on the quadrant of the resulting angle
Common Mistakes to Avoid
Degrees and radians can be used interchangeably in calculations without conversion
All trigonometric functions have the same period of 2π
sin(A + B) = sin A + sin B and cos(A + B) = cos A + cos B
