Reciprocal Identities
Each of the six trig functions has a reciprocal partner. This guide shows the three reciprocal identities, how to use them, and the mistakes to avoid. Quick answer: The reciprocal identities pair each trig function with its flip: csc θ = 1/sin θ, sec θ = 1/cos θ, and cot θ = 1/tan θ. They […]
How to Sketch Trigonometric Graphs?
To sketch a trigonometric graph, identify the amplitude, period, phase shift, and vertical shift from the equation, mark one full cycle using those values, then repeat it. Working from the parent graph outward keeps the transformations straight. Tutor-style math help Sketch Trigonometric Graphs: what to notice and how to work it Trigonometry skill A sine […]
