Getting Started With Simple Trig Prompts
I used to generate hundreds of trigonometry problems by hand. It was tedious and the quality was inconsistent. Now I use a prompt system that generates clean, readable trig problems with workable answers. This is what I learned doing it for about three years across high school tutoring and some curriculum writing. The basic approach is straightforward. You give the AI or tool specific instructions about triangle types, angle ranges, and answer formats. The result is a problem you can actually use in a worksheet or homework assignment. Most people overcomplicate this. You need to be precise about what you want. Here is a working prompt template I use regularly:
Generate a right triangle trigonometry problem. The triangle should have a right angle at C. Side a is 7 units, side b is 24 units. Ask students to find all three angles using inverse trig functions. Round answers to the nearest tenth. Provide the problem statement and a separate answer key with full work shown. This produces exactly what you need. The output is clean and the numbers actually work out. I tested this on roughly forty different versions before I stopped second-guessing the format. The tricky part is controlling the output so it does not produce nonsense. Sometimes the angles will not sum to one hundred eighty degrees due to rounding. That is fine for most classroom purposes but if you are building a test you need to verify the math yourself. I always run the generated problems through a quick check. I plug the values into a calculator and confirm the Pythagorean theorem holds and the angles add up. Takes about two minutes per problem set.
Another issue I ran into involves non-right triangles. Sine rule and cosine rule problems tend to produce ambiguous cases if you are not careful. The AI will occasionally generate a triangle where two different solutions exist but present it as if there is only one. I learned this the hard way when a student pointed out an error on a practice exam I had published. Since then I add a specific instruction to the prompt: specify whether the triangle is acute or obtuse, or tell the generator to only produce problems with a unique solution. That eliminates the ambiguity problem entirely. For more advanced work involving inverse trig functions, I recommend asking for problems that require composing two inverse functions. Something like finding sin(arccos(x)) or cos(arctan(y)). These are harder to generate correctly because the AI sometimes confuses the domain restrictions. I write a follow-up check prompt that asks the system to verify each answer by substituting back into the original expression. This catches about ninety percent of the errors before they reach the students. If you are looking to download a ready-made set of prompts, there are a few repos on GitHub that have decent collections. Search for trigonometry prompt generators and look for ones with recent updates. Most of them are a few years old and need some tweaking for current AI models. I spent about an afternoon updating one and it has worked well since then.

The main limitation of this approach is that you still need to understand trigonometry yourself. The prompts are a tool, not a replacement for knowledge. If you do not know how to verify a generated problem, you might hand out incorrect material. Budget some time for review even if the output looks correct on the surface. A properly reviewed set takes me about twenty minutes from start to finish including verification.
