Simplify Your Trigonometry Studies

Find all solutions for any trigonometric equation, showing the general solution and specific answers within a given interval.

Enter a complex trig expression to see it simplified step-by-step, or ask it to verify if an equation is a true identity.

Use the Law of Sines and the Law of Cosines to solve for unknown sides and angles in any triangle, not just right triangles.

Yes. Ask it to "graph $y = 2\cos(x - \pi/2)$" and our graphing calculator will plot the function, showing its amplitude, period, and phase shift.

Absolutely. It can solve and evaluate expressions involving arcsin, arccos, and arctan, providing answers in radians or degrees.

Yes, simply ask it to "convert $270^{\circ}$ to radians" or "convert $3\pi/2$ radians to degrees" for an instant, accurate answer.
