Question 1

Does it verify trig identities step by step?

Accepted Answer

Yes. It starts from one side and rewrites it one legal move per line until it matches the other side, with the identity used written beside each step. It does not skip to "both sides are equal."

Question 2

Can it graph functions with asymptotes and key points?

Accepted Answer

Yes. Rational functions come back with vertical, horizontal, and slant asymptotes dashed in, holes as open circles, and intercepts labeled. Trig graphs show amplitude, period, phase shift, and the five key points of one cycle.

Question 3

Does it solve trig equations on an interval and list every solution?

Accepted Answer

Yes. It isolates the trig function, finds the reference angle, places it in the correct quadrants, and lists every solution on the requested interval in radians or degrees, with the general solution if the problem asks for it.

Question 4

Does it follow the AP Precalculus free-response format?

Accepted Answer

The page is laid out the way AP Precalculus FRQs are scored: the function model written down, units stated, the calculation shown, and a justification sentence. If your teacher uses a specific template, paste it into the custom prompt and the page follows it.

Question 5

How is this different from a graphing calculator?

Accepted Answer

A calculator gives you the graph or the number. This gives you the method: why the asymptote is there, how the identity was rewritten, which rule applied at each step. The graph is drawn too, but as part of the worked page rather than the whole answer.

Question 6

Is there a free plan for precalculus help?

Accepted Answer

Yes. Three handwritten generations per month at no cost, with unlimited explanations and practice problems on every plan. Paid options are the $4.99 Weekly Pass or monthly plans from $7.
