tan 2x/1+sec 2x = tanx - Brainly.in

To integrate sec^2x, also written as ∫sec 2 x dx, sec squared x, and (sec x)^2, we start by using standard trig identities to simplify the integral. We begin by rearranging the standard trig identity tan 2 x = sec 2 x-1 for sec 2 x. Hence our original integration problem can be rewritten as shown above...A ray of light passes from a medium X to another medium Y. No refraction of light occurs if the ray of light hits the boundary of medium Y at an angle of: Write each of the following as a decimal.(a) Three hundred six and seven-hundredths(b) Eleven point two three five(c) Nine and twenty five thousandths.Meta Stack Exchange.tan(theta) = sin(theta) / cos(theta) = a / b.

Thanks Alan, I doubt I would have got that on my own EVEN if I had been a good enother forensic mathematician to work out the question in the first place.Not necessarily the simplest: tan(x)= sin(x)/cos(x) and sec(x)= 1/cos(x) so tan^2(x) sec(x)= sin^2(x) The second integral, upon multiplying both the numerator and denominator by (sec x + tan x), evaluates to log |sec x + tan You're probably thinking of the u = tan(x/2) thing I mentioned above.

Cece,

I believe you might be just overthinking it. Here's the statement that we're comparing, a minimum of as I'm studying the query:

(*1*)

The identification, as you famous, is tan2x + 1 = sec2x, for all values of x. Rearranging, you completely get:

tan2x - sec2x = 1.

So, the unique observation is fake. Sure, there could be values of x for which the unique equation works. It's solvable, but that doesn't make it true for all x.

When you began messing with the equation by rewriting it as sines and cosines, I feel you goofed the mathematics:

sin2x/cos2x + 1/cos2x = 1.

After that, you said you'll get sin2x/cos2x = 1, which is not true. Ya misplaced the second term there, the 1/cos2x. If you multiply the entire thing through cos2x, you'll get:

sin2x + 1 = cos2x.

This brings us back to sines and cosines, and it is still now not true for all x. Therefore, it's still false. :)

So sure, whilst you firstly in comparison this to the identification you understand for secants and tangents, that used to be how I was occupied with it, too. It's now not the same, so it's not true for all x.
