Interpretation of trigonometric graph of y = a sin x and y = a cos x.
Amplitude is a indication of how much energy a wave contains. Graphs of y = a sin bx and y = a cos bx introduces the period of a trigonometric graph. Graphs of y = a sin(bx + c) and y = a cos(bx + c) helps you to understand the displacement (or phase shift) of a trigonometric curve.
Unit circle is the source for the generation of the trigonometric function graphs. The quadrants from the unit circle, when placed horizontally in numerical order, create the basis for the trigonometric graphs. Hence This process of creating graphs from the unit circle is often called “unwrapping” the unit circle. Unit circle with Trigo Graph
General Solutions of a Trig Equation. From the following diagram we see that sin( π -θ) = sin θ and cos ( -θ) = cos θ. General Solution of trigonometric eq
Trigonometric Equation involve one or more trigonometric ratios of unknown angles. Due to difference unit of angle , hence it gives angle in different form. Similarly it give value in radian. Trigonometric equation
