In mathematics, an "identity" is an equation which is always true These can be "trivially" true, like " x = x " or usefully true, such as the Pythagorean Theorem's " a2 b2 = c2 " for right triangles There are loads of trigonometric identities, but the following areTan^2xtan^2y=sec^2xsec^2y and, how do you factor and simplify, cscx(sin^2xcos^2xtanx)/sinxcosx calculus identities prove this identity sec(y) cos(y)= tan(y)sin(y) THANK YOU!!Get an answer for 'Verify the following identity `tanx(cot x tan x) = sec^2x`' and find homework help for other Math questions at eNotes

Sec^2x tan^2x identity
Sec^2x tan^2x identity-I need to prove that $$1\tan x \tan 2x = \sec 2x$$ I started this by making sec 1/cos and using the double angle identity for that and it didn't work at all in any way ever Not sure why I can't do that, but something was wrongWelcome to Sarthaks eConnect A unique platform where students can interact with teachers/experts/students to get solutions to their queries Students (upto class 102) preparing for All Government Exams, CBSE Board Exam, ICSE Board Exam, State Board Exam, JEE (MainsAdvance) and NEET can ask questions from any subject and get quick answers by
Which Of The Following Are Trigonometric Identitie Gauthmath
In mathematics, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined Geometrically, these are identities involving certain functions of one or more anglesThey are distinct from triangle identities, which are identities potentially involving angles but alsoNow there are various ways to see it Of course it is easier knowing the standard identities and using them, but they all pretty much boil down to sin 2 x cos 2 x = 1, which is in turn another way of writing Pythagoras, and which will definitely help here$$\tan 2x \neq \sec 2x \sin 2x \cos 2x $$ Based on the proof computed above, the given equation is not an identity Become a member and unlock all Study Answers

Yes, sec 2 x−1=tan 2 x is an identity sec 2 −1=tan 2 x Let us derive the equation We know the identity sin 2 (x)cos 2 (x)=1 ——(i) Dividing throughout the equation by cos 2 (x) We get sin 2 (x)/cos 2 (x) cos 2 (x)/cos 2 (x) = 1/cos 2 (x) We know that sin 2 (x)/cos 2 (x)= tan 2 (x), and cos 2 (x)/cos 2 (x) = 1 So the equation (i) after substituting becomes How do you verify the equation is an identity?Free math lessons and math homework help from basic math to algebra, geometry and beyond Students, teachers, parents, and everyone can find solutions to their math problems instantly
