WebAt a point x = a x = a, the derivative is defined to be f ′(a) = lim h→0 f(a+h)−f(h) h f ′ ( a) = lim h → 0 f ( a + h) − f ( h) h. This limit is not guaranteed to exist, but if it does, f (x) f ( x) is said to be differentiable at x = a x = a. Geometrically speaking, f ′(a) f ′ ( a) is the slope of the tangent line of f (x) f ( x) at x = a x = a.

WebThis isn't a different conclusion from yours, but it is a different route. arccos(x)+arcsin(x) is a constant 2π, which can be seen geometrically or with calculus. So then you have arccos(x)− (2π − arccos(x)) = 2arccos(x)− 2π Prove sec2x+ tan2x ≡ cosx−sinxcosx+sinx WebDifferentiate tan 2 x with respect to x, using the chain rule we get. d d x tan 2 x = sec 2 2 x d d x 2 x. ⇒ d d x tan 2 x = sec 2 2 x · 2. ⇒ d d x tan 2 x = 2 sec 2 2 x.

WebNov 13, 2024 · From above, we found that the first derivative of sec(2x) = 2sec(2x)tan(2x). So to find the second derivative of sec(2x), we just need to differentiate 2sec(2x)tan(2x) We can use the chain rule to find the derivative of 2sec(2x)tan(2x) and it gives us a result of 8sec 3 (2x) – 4sec(2x) The second derivative of sec(2x) is 8sec 3 (2x) – 4sec(2x) WebYou're correct that the derivative of tan (x) is sec² (x), or 1/cos² (x). cos (3π/4)=-√2/2, so this equals 1/ (-√2/2)²=1/ (1/2)=2. 3 comments ( 3 votes) siddiqah.ali0324 5 years ago Why is cos+sin equal to 1? • ( 2 votes) NoahJpancake 5 years ago By the way, it's cos^2+sin^2=1. grammy best new artist 2023
