Feb 04, 2010 · Thus (1 + sinx + cosx)(1 - cosx) = sinx(1 + sinx - cosx). Now divide both sides by (1 + sinx - cosx)(1 - cosx) to arrive at the desired identity. 0 0. Anonymous. 1

Another identity is that 2 sin x cos x = sin 2x, so you end up with. 1 + sin 2x Feb 24, 2009 · The denominator is a difference of squares, so you get 1-sin^2 x. what you have now is. cosx(1+sinx) / 1-sin^2x. You know that 1-sin^2x is equal to cos^2x. so know you have.

(sinx - cosx + 1)/(sinx + cosx - 1) = (sinx + 1)/cosx

cosx(1+sinx) / 1-sin^2x. You know that 1-sin^2x is equal to cos^2x. so know you have.

1-sinx=cos2x. ***. for interval: [0,π/2] .. sinx=0. x=0. Mar 27, 2011 · Simplify the LHS by first getting a common denominator of sin(x)*(1 + cos(x)).

cosx(1+sinx) / 1-sin^2x. You know that 1-sin^2x is equal to cos^2x. so know you have. cosx(1+sinx) / cos^2x. get rid of the cosx on top by simplifying and the cos^2x so that you're left with (1+sinx) / cos x.

Misc 9 Find sin /2, cos /2 and tan /2 for cos = 1/3 , in quadrant III Since x is in quadrant III 180 < x < 270 Dividing by 2 all sides (180 )/2 < /2 < (270 )/2 90 < /2 < 135 So, /2 lies in IInd quadrant In IInd quadrant, sin is positive, cos & tan are negative sin /2 Positive and cos /2 and tan /2 negative Given, cos x = 1/3 cos x = 2 cos2 /2 1 1/3 = 2cos2 /2 1 1 1/3 = 2cos2 /2 (3 ?(x+sinx)/(1+cosx)dx = Find the answer to this question along with unlimited Maths questions and prepare better for JEE 2020 exam.

Therefore sinx + cosx ≥ sin 2 x + cos 2 x = 1. Last edited: Apr 30, 2010 I= log[(1+sinx)/(2+sinx)] …..this is the alternative way. Method 2:-I = integration [cosx /(1+sinx)(2+sinx)]dx. Since derivative of (1+sinx) or (2+sinx ) w.r.t x is cosx and it is available in question.

So the only solutions are x=pi, x=3pi/2. A much simpler way to find the answer is to observe graphically that the line x + y = -1 crosses the unit circle at (-1,0) and (0,-1) and therefore sin t + cos t = 1 1/ sinx(1 + cosx) = 1 + cosx + cos^2x 2/ sin^3x + cos^3x = sinx - cosx 3/ 3 cos^4x -4 sin^2xcos^2x + sin^4x = 0 Đăng chủ đề mới Cộng đồng học sinh Việt Nam - HOCMAI Forum Algebra -> Equations-> SOLUTION: Prove the identity ; (Cosx / 1 -sinx) - ( cosx / 1 +sinx) = 2tanx Log On Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.
