Prove that (sinx-cosx+1)/(sinx+cos-1)=secx+tanx. Answer. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.Since 1 ≥ (sinx, cosx) ≥ 0 in the interval, sinx ≥ sin2x and cosx ≥ cos2x. Is there any non geometrical way to proof this fact? sinx+cosx>=1 for every x in [0,Pi/2].i was gonna divide by cosx after moving the sinx to make a tan but that -1 gets in the way...grrrrr help is Anonymous asked in Science & Mathematics. Mathematics · 1 decade ago. sinx + cosx = -1?
Sinx+cosx> = 1 | Physics Forums
if sin (x) or cos (x) are 0 and for no other value. Good enough. if you're taking the square root, you take the WHOLE equation. you can't just square root cosx^2 and sinx^2 separately. that's only when...What is sin x/cos x? Peter Butcher. How do I find the maximum value of sinx - cosx? Is cos^2x and (cos x)^2 the same thing?[math](cos\frac\pi4sinx+sin\frac\pi4cosx)=\frac1{\sqrt2}[/math].
sinx + cosx = -1? | Yahoo Answers
Now divide by (sinx)(1-cosx). Please help me verify this identity? tan(x + pi/4) = (cosx + sinx)/(cosx - sinx)?cosx/1+sinx + 1+sinx/cosx = 2sec. I'd like to know how to solve this problem. We are learning trigonometric identities.(cosx)/(sinx-1) = 0. 0.#rsinxcosa+rcosxsina=1#. #sinx+cosx=1#. Therefore How do you solve for x in #3sin2x=cos2x# for the interval #0 ≤ x < 2π#. See all questions in Solving Trigonometric Equations.
