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

May 22, 2008 · combine the fractions. cos^2 x + (1-sin x)^2 / [cos x* (1-sin x)]=2sec x. simplify a little. (cos^2 x + 1 - 2sin x + sin^2 x)/ [cos x* (1-sin x)]=2sec x. use Pythagorean trig identity. 2 (1 - sin x)/ [cos x* (1-sin x)]=2sec x. factor out the (1-sin x) 2*1/cos x=2sec x. definition of secant.

(round your answers to four decimal places.) (a) if the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51? sinx,cosx I will work on my sinx and cosx. Thanks for your help. Tim answer choices: a. sinx b.

1 + sinx = sin^2(x/2) +cos^2((x/2) + 2sin(x/2)*cos(x/2) ={sin(x/2) +cos(x/2)}^2 Similarly, 1-sinx = sin^2(x/2)+cos^2(x/2) - 2sin(x/2)*cos(x/2) ={sin(x/2)- cos(x/2)}^2 sinx sinxcos x sin x−= 23. 5.Prove: cosx 1 sinx 2secx 1 sinx cosx + + = + 6.Prove: 2 cscxcosx cos x tanx cotx = + 7.Prove: 44 22 sin x cos x 1 sin x cos x − = − 8.Prove: 2 2 2. tan x sin x tan x 1 = + 9.Prove: 1 sinx cosx cosx 1 sinx − = + 10.Prove: tan x csc xtan x 1. 2 22=− 11.Prove: cosx secx tanx 1 sinx += − 12.Prove: cscx cotx Nov 30, 2013 · Recall the formula tanA = sinA/cosA.

The sum would be (cos^2x +1-2sinx +sin^2x)/[(1-sinx)cosx] =(2-2Sin x)/[(1-sinx)cosx] =2/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). 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!
