We had learned Basics of Trigonometry in Class 10. In this chapter, we will learn

  • What is a positive or a negative angle
  • Measuring angles in Degree, Minutes and Seconds
  • Radian measure of an angle
  • Converting Degree to Radians, and vice-versa
  • Sign of sin, cos, tan in all 4 quadrants
  • Finding values of trigonometric functions when one value is given (Example: Finding value of sin, cot, cosec, tan, sec, when cos x = -3/5 is given)
  • Finding Value of trigonometric functions, given angle
  • Solving questions by formula like  (x + y) formula, 2x 3x formula, Cos x + cos y formula , 2 sin x sin y formula 
  • Finding principal and general solutions of a trigonometric equation
  • Sin and Cosine Formula with supplementary Questions
