Trigonometric equations and their general solutions are crucial topics in Class 12 Basic Mathematics, offering a deeper understanding of trigonometric functions and their applications. Mastery of this topic prepares students for NEB examinations and develops problem-solving skills essential for advanced mathematics. To support students, we have created a comprehensive Trigonometric Equations and General Values Guide and Solution.
This guide is based on the Class 12 Basic Mathematics textbook approved by the Curriculum Development Center of Nepal. It provides detailed explanations, step-by-step solutions, and practical tips to help students excel in their exams and assignments.
Understanding Trigonometric Equations
A trigonometric equation involves one or more trigonometric functions, such as sine (), cosine (), or tangent (). Solving these equations requires determining the values of the variable (typically an angle) that satisfy the equation. For instance, solving involves finding all angles that satisfy the equation within a given interval or for all possible values.
The guide explains the methods for solving trigonometric equations step-by-step:
- Basic Solutions: Finding specific solutions for equations using standard trigonometric values.
- General Solutions: Deriving the general form of solutions by incorporating the periodicity of trigonometric functions. For example:
- has a general solution or .
- has a general solution .
