Prove cosФ(tanФ)/sinФ = sec²Ф-tan²Ф

yung cosФ sa left side ay kokopyahin mo lang tapos dun naman sa tanФ.. yung tanФ ay magiging sinФ/cosФ tapos kokopyahin yung over sinФ .. edi ba, makacancel lahat ng yun .. kaya ang sagot sa left side ay 1 kasi nacancel lahat.. tapos dun naman sa right side, yung sec²Ф ay magiging 1-tan²Ф (given na yang formula na yan, yan ay fundamental identities) tas kokopyahin mo lang yung tan²Ф tapos makacancel yung tan²Ф at -tan²Ф kaya ang natira ay 1. at ang final answer ay 1=1. :)) gets na?

:)) hahahahahahahaha.. tawa muna! XDXD


CosФ (sinФ/cosФ)/sinФ = sec^2Ф - tan^2Ф
1 = 1 - tan^2
Ф - tan^2Ф
1 = 1 ..

macacancell yung left side kaya 1 tas dun sa right side naman ay ang macacancel ay yung tan^2
