Prove that Cosx/(1-Sinx) = (1+Cosx+Sinx)/(1+Cosx-Sinx) i) Grouping the given one, it is: { (1 - cosx) + sinx}/ { (1 + cosx) + sinx} ii) By multiple/sub multiple angle identities, 1 - cosx = 2*sin² (x/2); 1 + cosx = 2*cos² (x/2) and sin (x) = 2*sin (x/2)*cos (x/2) iii) Substituting these in (i) above, Left side = {2*sin² (x/2) + 2*sin (x/2)*cos (x/2)}/ {2*cos² (x/2) + 2*sin (x/2)*cos (x/2)} 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 Trigonometry Formula List: https://www.youtube.com/watch?v=EaSV-VasbnQ&list=PLJ-ma5dJyAqqEv5UpYmUFj6PVyMpHrLZ6&index=1 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 Solve your math problems using our free math solver with step-by-step solutions.

In order to prove the trigonometric identity, we need to start with one side and use known identities to get to the other side: `LS={1-sinx}/cosx` multiply by 1+sinx in numerator and denominator Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Dec 07, 2007 · 1. ( secx/sinx) - (sinx/cosx) = ( 1 / sin x cos x) - ( sinx / cos x) = ( 1 - sin^2 x)/ (sin x cos x) = cos^2 x / (sin x cos x) = cos x / sin x = cot x ans.

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. cosx(1+sinx) / cos^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. 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. Therefore cosx / 1- sinx = 1 + sinx / cos x sin(2x)=1. Take the inverse sine of both sides of the equation to extract from inside the sine. The exact value of is . en. Related Symbolab blog posts.
