DAT “How Fast Can You Solve This? DAT-Style Trig Question Inside!”

This forum made possible through the generous support of SDN members, donors, and sponsors. Thank you.
f sin A = 3/5 and angle A is acute, what is cos A?


(Don’t peek before you try!)


Check the attached image for the solution, step-by-step explanation, and more DAT-style math practice.


For anyone struggling with math on the DAT, remember: building confidence with quick triangle sketches and trig relationships is key!


Bonus Info for 2025 DAT Takers:
The recent DAT updates changed the scoring scale, but the actual math content—including trigonometry—remains the same. The Quantitative Reasoning section still covers the basics:


  • SOH-CAH-TOA
  • The Pythagorean theorem
  • Simple right triangle ratios

You don’t need to memorize advanced trig identities for the DAT. But don’t skip reviewing these fundamentals—trig may only be a small part of QR, but it’s an easy spot to pick up points if you’re ready for it!
