Homework Statement
I don't understand the step the math book took to convert sin(theta)/sin(theta)-cos(theta) to 1/sin(theta)-cos(theta)/sin(theta)
Solving Trig Theta Question: 1/sin(theta)-cos(theta)/sin(theta)
Click For Summary
SUMMARY
The forum discussion centers on the mathematical transformation of the expression sin(theta)/sin(theta) - cos(theta) into 1/sin(theta) - cos(theta)/sin(theta). The user expresses confusion regarding the validity of this transformation, asserting that while dividing the entire expression by sin(theta) yields the latter form, it does not hold true that 1 - cos(theta) equals 1/sin(theta) - cos(theta)/sin(theta). This highlights a common misunderstanding in trigonometric identities and algebraic manipulation.
