Well, i tried to see the beauty in trigonometry but to me, it is just too HARD!!!!!!!! There r so many formulae in trigonometry and how to i know which one to use. After i stay in the desk for 15 mins, i just wanna throw this stupid book away. I cant gain anything even i try ...

**trigonometry**

This is not a trigonometry question. x^2 + 7x + (7/2)^2 = 11 + (7/2)^2 (x + 7/2)^2 = 23 1/4 x = -7/2 +/- sqrt(93)/2

I am surprised that you are studying trigonometry and don't know the basic shape of y = sinx Surely your instructor has taught you how to sketch the basic graphs before jumping to technology methods.

i know an education is important, but i don't think i'll need to know u.s. history, or trigonometry in the future. i plan on doing something in the cooking field as a career, and most people i know who do that didn't really get good grades on their trigonometry classes.

**algebra 2 with trigonometry**

What is the problem? (6t-4)-(6t2+t-2) = 6t - 4 - 6t^2 - t + 2 = -6t^2 + 5t - 2 Why did you label this algebra2 ? Secondly where does the trigonometry enter the picture?

Do you mean (5d -1)^4 ? Square 5d -1 twice. The first squaring will give you 25d^2 -10d +1 Now square that. There will be more terms next time. This is not 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

**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.
