WebIn equation cosxsinx=sinx 2cosx we shouldn’t divide by cosx because we might lose solutions( cosx=0) . Correct. if we do we are essentially dividing by zero, how is this possible? How is what possible? You said it yourself: by dividing by cos(x), you are assuming cos(x) to be non-zero, and therefore ignoring the solution cos(x)=0. While the early study of trigonometry can be traced to antiquity, the trigonometric functions as they are in use today were developed in the medieval period. The chord function was discovered by Hipparchus of Nicaea (180–125 BCE) and Ptolemy of Roman Egypt (90–165 CE).
