12 Mar 2015 cosx/1+sinx + 1+sinx/cosx = 2sec. I'd like to know how to solve this problem. We are learning trigonometric identities. Follow 7 Aug 2017 Ill assume its the first one.cos x / ( 1 + sin x) + (1 + sinx ) / cos x= cos^2 x + Verify the identity cosx/1+sinx + 1+sin/cosx = 2sec x. 1. See answer. Cosx/1-sinx + 1-sinx/cosx = 2secx.

## Which one is equivalent to: $$\frac{1-\sin(x)+\cos(x)}{1+\sin(x)+\cos(x)}$$ 1)$\dfrac{\cos(x)}{1+\sin(x)}$ 2)$\dfrac{\cos(x)}{1-\sin(x)}$ 3)$\dfrac{1-\sin(x)}{\cos(x

:) I tried forever on itand did not get it right Question : cosx/1-sinx=1+sinx/cosx Let's work with the left hand side We're going to times cosx/1-sinx by 1+sinx/1+sinx, you can do this because 1+sinx/1+sinx is equal to 1, so you aren't really changing anything. Trigonometric Identities and Formulas. Below are some of the most important definitions, identities and formulas in trigonometry.

### (cosx) / (1 + sinx) + (1 + sinx) / (cosx) = 2secx. The first thing you should do is choose the more complex side. In this case, it's the left hand side (LHS). LHS = (cosx) / (1 + sinx) + (1 + sinx)

= 2− 2sinx (1 −sinx)cosx. = 2 cosx. =2secx. Answer link. Most of the work is simple algebra.

In this case, it's the left hand side (LHS). Question : cosx/1-sinx=1+sinx/cosx Let's work with the left hand side We're going to times cosx/1-sinx by 1+sinx/1+sinx, you can do this because 1+sinx/1+sinx is equal to 1, so you aren't really changing anything. Simplify the LHS by first getting a common denominator of sin(x)*(1 + cos(x)). LHS becomes: [(1 + cos(x)) - sin²(x)]/[sin(x)*(1 + cos(x))] = [(1 + cos(x)) - (1 You can put this solution on YOUR website! Prove that: Cosx/1-sinx + 1-sinx/cosx = 2secx----- Multiplying left-side by LCD, (1 - sin x)(cos x)----- Substituting 1 for Get an answer for 'Verify: (cosx/1 + sinx) + (cosx/1-sinx) = 2secx' and find homework help for other Math questions at eNotes We’ve discounted annual subscriptions by 50% for COVID-19 relief answer choices: a. sinx b. 2secx c.

------- Multiplying left-side by LCD, (1 - sin x) (cos x) ----- Substituting 1 for. (cosx) / (1 + sinx) + (1 + sinx) / (cosx) = 2secx. The first thing you should do is choose the more complex side. In this case, it's the left hand side (LHS). LHS = (cosx) / (1 + sinx) + (1 + sinx) Feb 17, 2008 · Question : cosx/1-sinx=1+sinx/cosx Let's work with the left hand side We're going to times cosx/1-sinx by 1+sinx/1+sinx, you can do this because 1+sinx/1+sinx is equal to 1, so you aren't really changing anything.

Zjednodušte Explanation: ( cos(x) 1 + sin(x)) +( 1 + sin(x) cos(x)) = cos2(x) +1 + 2sin(x) + sin2(x) cos(x)(1 +sin(x) = 2 +2sin(x) cos(x)(1 +sin(x)) = 2 cos(x) = 2 ⋅ 1 cos(x) = 2sec(x) Answer link.
