Answer :

A**Explain Trignometric Ratios or Function with graph .**

**Trigonometric ratios are same for same angle**

**Relation between trigonometric ratios**

**State Fundamental Trigonometric identities and also prove that identities .**

**Prove related problems - Type 1 - prove the following identities `(1) sin^8theta-cos^8theta=(sin^2theta-cos^2theta)(1-2sin^2thetacos^2theta (2) cot^2 theta+cot^4theta=cosec^4theta-cosec^2theta`**

**Prove related problems - Type 2-(1) If `cos theta+sintheta=sqrt2costheta` prove that `cos theta-sin theta=sqrt2 sin theta`(2) Given that `(1+cos alpha)(1+cos beta)(1+cos gamma)=(1-cosalpha)(1-cosbeta)(1-cosgamma)` Show that the value of each member of the equality is `sinalphasinbetasingamma`**
