How to Prove Trigonometric Identities Sec2A – Tan2A = 1 Proof
Hi Friends, In this video we are going to learn another very important trigonometry identity which Sec^2X + Tan^2X = 1. This identity will be very helpful in future so keep in mind and see we derive this formula too.
I hope you understand the concept hidden inside this trigonometry identity or formula. Now lets learn next level trigonometry tutorial videos.
