I am preparing for the Pre-Calculus finals tomorrow and I have 3 questions on the practice review. A. sin^2 theta + _____ = 1B. tan^2 theta + 1 = _____C. 1 + _____ = csc^2 theta I am not looking for the answers I am looking more for the trigonometric equation that got this information, I forgot the excact one but I thought it was something like sin^2 theta + cos^2 theta = 1 but I can't be sure, please help! Thank you!
