Math, asked by VRMvaishnavimali, 1 year ago

If sin theta +sin^2theta=1
Prove that cos^2theta +cos^4theta=1

VRMvaishnavimali: Let @represent theta

VRMvaishnavimali: Sin@+sin2@=1.

VRMvaishnavimali: Sin@+1-cos2@=1

VRMvaishnavimali: Sin@=cos2@

VRMvaishnavimali: Squaring both sides

VRMvaishnavimali: Sin2@=cos4@

VRMvaishnavimali: 1-cos2@=cos4@

VRMvaishnavimali: 1=cos2@+cos4@

VRMvaishnavimali: Hence proved
