Use a graphing calculator to solve the equation - 3 cos t = 1 in the interval from 0 ≤ theta ≤ 2 π round to the nearest hundredth.

Why would the crystals in an intrusive igneous rock be larger than the crystals in a chemical sedimentary rock? a. intrusive rocks form beneath the earth's surface, so they cool very slowly, which produces larger crystals. b. chemical sedimentary rocks form from dissolved substances on the earth's surface with very high heat and cool very slowly, which produces smaller crystals. c. chemical sedimentary rocks and intrusive rocks have crystals of the same size. o d. chemical sedimentary rocks form deep in the earth, so they cool slower, which produces small crystals. € read question correct:
