That's called using L'Hopital's rule for indeterminate-ratio limits. It works for 0/0 or infinity/infinity. Try it with a number close to pi/4, such as 0.785, and you will see that it gives the right answer.... 10/08/2014 · Polynomial Question: How would I solve this polynomial word problem? Let x, y, z be real numbers such that xyz = x^3 - 2 = y^3 - 6 = z^3 - 20. Find the greatest possible value of x^3 + y^3 + z^3.?

**How do I solve lim(x-->pi/4)(sinx-cosx)/cos(2x) The (x**

But we know that cosX can't be bigger than 1 or less than -1, so we can safely reject cosX=-2, and solve cosX=1/2. This is one of those familiar angles, X=60 degrees or (pi)/3 radians. Now you need to remember which quadrants cosine is positive in. ASTC (All Silver Tea Cups: All trigs, sin, tan, cos) for Q1 to 4. So cosine is positive in Q1 and Q4. The solution therefore is (pi)/3 and 2(pi... That's called using L'Hopital's rule for indeterminate-ratio limits. It works for 0/0 or infinity/infinity.

You can put this solution on YOUR website! Not very easy to solve this algebraically, since trigonometric functions are transcendental (meaning "not algebraic"), and most equations that combine transcendental and algebraic functions cannot be solved algebraically. how to send a calendar from my mac to iphone 3/03/2011 · Best Answer: Hints: a) is the same as 2sinx = cosx, which if you divide by cosine will give you an equation with just one trig function, the tangent. b) is missing part of the equation, so I cannot comment on it. c) Replace cos^2 x in terms of sin^2 x , and then solve the resulting equation -- …

- I would like to know how can we solve the equation $\cos x = x$, without graphing. I know that there would only be one solution, that is obvious, that too in between $0$ and $\frac{\pi}{2}$.

- 1. Introduction In this unit we look at how to diﬀerentiate the functions f(x) = sinx and f(x) = cosx from ﬁrst principles. We need to remind ourselves of some familiar results.
