Purdue University - Physics Laboratories 2 Part 2. Trigonometry 5. y 3 cm x ! sin ! = 0.60 x = ______________ y = ______________ 6. If sin 35˚ = cos " , then = _____________ 7. If sin = 0.80, then cos = _____________ and tan = _____________ 8. ! Mark all angles that are equal to the angle . How many did you mark (including the one that was already marked)? _____________ 9. For what values of , if any, is the following expression true? sin 2 + cos 2 = 2.0 = ____________________________ Part 3. Scientific Notation In scientific work, it is convenient to express numbers as the product of a number between 1 and 10 multiplied by an appropriate power of 10. Thus 0.00050 becomes 5.0 " 10 -4 , and 1,800,000 is written as 1.8 " 10 6 . This way of writing numbers is called scientific (or powers of ten) notation.
