WebSo, in order for this substitution to work out okay, you're letting x=a*tan(theta) so that when you write it out, you will end up with a^2+(a*tan(theta))^2 in your denominator. Simplifying leads to a^2+(a^2 * tan^2(theta)), and factoring the a^2 out gets: a^2(1+tan^2(theta)). Much like this video, it is basically the same process, just keeping ...

Derivative of Tan x - Formula, Proof, Examples - Cuemath
WebTrigonometry. Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. 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 … how millennials invest hong kong
