Question

Using trig identities, transform the left side into the right:
sin(x)/cos(x) + cos(x)/sin(x) = csc(x)sec(x)

Answer 1

sum up the left-hand side, what does it give you?

Answer 2

Wouldn't you need a common denominator for the fraction before you add the left hand side?

Answer 3

yes, so what would that be?

Answer 4

a value, that both denominators can divide

Answer 5

doesn't have to be the LEAST

Answer 6

anyyhow.... the LCD will be the product of both denominators
so... what does that give you on the left-hand side?

Answer 7

\(\bf \cfrac{sin(x)}{cos(x)}+\cfrac{cos(x)}{sin(x)} = \cfrac{\square? + \square?}{cos(x)sin(x)}\)
