Sep 18, 2012 · There is the good response here, and I particularly agree with this because this generally makes the simplification a bit simple. Don't forget that you have the function as the exponent of … lim x-> pi/4 of (1-tanx)/(sinx-cosx) - Brainly.com To evaluate the expression Lim x-> pi/4 of (1-tanx)/(sinx-cosx), the first thing to do is to substitute x with pi/4. In this case, the answer is 0/0 or indeterminate. using L'hopital's rule, we derive separately the numerator and the denominator resulting to 1- sec2 x / (cos x + sin x). substituting again, the answer is … Lim (sinx-cosx)/(pi-4x) where x->pi/4 | Physics Forums Jan 09, 2010 · lim (sinx-cosx)/(pi-4x) where x-->pi/4 Hi! Could someone help me to solve this problem without using L'Hospital rule? Any hint would be splendid

Dec 07, 2015 · Como se hace limx tiende a pi/4 de (1-tanx)/(cos x - senx) Recibe ahora mismo las respuestas que necesitas! Prove this identity: $ \\tan(2x)-\\sec(2x) =\\tan(x-\\pi/4)$ I then tried the right side and had a little more luck but I've hit a block. I first used the tan difference identity then converted everything into sins and cosines. Then I used a difference identity on sin and cosine and then converted into exact values. $\dfrac{\pi}{4}$ for sine and cosine is $\dfrac{\sqrt{2}}{2}$. lim x-pi/4 (1-tanx) / (x-pi/4) - Math - - 3138437 ...
