Overte identitu cosx 1 + sinx + 1 + sinx cosx = 2secx

:) 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.

Overte identitu cosx 1 + sinx + 1 + sinx cosx = 2secx

(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.
