Some Trigonometry Tips and Tricks

COOL TRIGO. TIPS AND TRICKS

By learning these trick you shall be surely able to solve problems a bit faster.

So lets get started,

Consider a triangle ABC, right angled at C.

So here these can be learned--->

c = b.secA                                    b = c.cosA                                      a = c.sinA

c= a.cosecA                                 b = a.cotA                                       a = b.tanA

These eq. serve a great help for height and distance questions.

Also, these eq. can also be memorised, --->

tanA/secA = sinA

cotA/cosecA = cosA

SO thats it........coming for more such tricks.
