Use compound angle identities in proof - identity selection
For acute angles \(A\) and \(B\), \(\sin A=7/25\), \(\cos A=24/25\), \(\sin B=3/5\), and \(\cos B=4/5\). Enter \(\sin(A+B)\).
Worked practice: result and interpretation
Calculate the requested result first, then choose the interpretation that follows from it.
Write a full answer
Now write the response in full, in your own words — this is what the exam asks for. The AI marks it on the same moves you built above (focus, evidence, technique, judgement) and gives feedback on reasoning, evidence, and expression.
