Considering the unit circle, the six important trigonometric functions are given as follows: If “n” is an integer, then. Sin x =0 ⇒ x =nπ. Cos x = 0 ⇒ x= (2n+1)π/2. The other trigonometric functions in terms of sine and cosine functions are given as follows: Tan x = sin x /cos x ⇒ x≠ (2n+1)π/2. Cosec x = 1/sin x ⇒x ≠ nπ,.

Dec 09, 2016 · Tip 4) Use Pythagorean Identities to transform between sin²x and cos²x. Pay special attention to addition of squared trigonometry terms. Apply the Pythagorean identities when necessary. Especially sin²x+cos²x=1 since all the other trigo terms have been converted into sine and cosine. This identity can be used to convert into and vice versa..

  • Make all of your mistakes early in life. The more tough lessons early on, the fewer errors you make later.
  • Always make your living doing something you enjoy.
  • Be intellectually competitive. The key to research is to assimilate as much data as possible in order to be to the first to sense a major change.
  • Make good decisions even with incomplete information. You will never have all the information you need. What matters is what you do with the information you have.
  • Always trust your intuition, which resembles a hidden supercomputer in the mind. It can help you do the right thing at the right time if you give it a chance.
  • Don't make small investments. If you're going to put money at risk, make sure the reward is high enough to justify the time and effort you put into the investment decision.
