General solution: find the angles in the interval that satisfy the equation and add multiples of the period to each answer.The perpendicular bisector of a chord passes through the centre of the circle. Restricted values: find the angles that lie within a specified interval by adding/subtracting multiples of the appropriate period. The line drawn from the centre of a circle perpendicular to the chord bisects the chord.Use the CAST diagram to determine where the function is positive or negative (depending on the given equation/information).Determine the reference angle (use a positive value).Simplify the equation using algebraic methods and trigonometric identities.We know that the sine and cosine functions have a period of 360360° and the tangent function has a period of 180180°. If we do not restrict the solution, then we need to determine the general solution to the equation. The periodicity of the trigonometric functions means that there are an infinite number of positive and negative angles that satisfy an equation. How to solve general trigonometric equations formula and find solutions Solutions Trigonometric Equations Equations Below here is the table defining the general solutions of the given trigonometric functions involved equations. Similarly, general solution for cos x = 0 will be x = (2n+1)π/2, n∈I, as cos x has a value equal to 0 at π/2, 3π/2, 5π/2, -7π/2, -11π/2 etc. Hence, the general solution for sin x = 0 will be, x = nπ, where n∈I. The principal solution for this case will be x = 0, π, 2π as these values satisfy the given equation lying in the interval. Will start with the basic equation, sin x = 0.
