**trigonometry**

determine the trend of each linear function: 1. f(x)= 3x+5 I don't know what you call the "trend" or why you call this a trigonometry question. It is about algebra. The value of the function increases with x at a rate of three times the change in x.

**Math (trigonometry)**

Trigonometry identities are so hard... I need some help proving these identities: *Oh, and I'm only in grade 11, so the identities we use are quotient identity and Pythagorean identity. sinx/(sinx + cosx) = tanx/(1 + tanx) cos^2x - sin^2x = 2cos^2x - 1 Thanks! Lucy
