CBSE Class 10 - Introduction to Trigonometric Identities Videos
Trigonometric identity : cosec^2x - cot^2x = 1
The video explains a question based on trigonometric identity cosec^2x - cot^2x = 1
-
sinA(1+tanA)+CosA(1+cotA)=seA+cosecA
- Sin^2A/2+Sin^2(B+C/2)
- prove that 1+sina-cosa/1+sina+cosa=√1-cos/√1+cosa
- sin teta + 2cos teta =1 prove that 2sin teta - cos teta =2
- Cosec²72° - tan²18°=1
-
- Show that … cosec theta minus 2sin cube theta upon 2cos cube theta minus cos theta is equals to tan theta
