Question

$cot {}^{2} - tan {}^{2} = cosec { }^{2} - sec {}^{2}$
plz give me ans
​

Answer 1

COT²-TAN²=COSEC²-SEC²

SO

WE'LL

put cot²=cosec²-1

sec²=1+tan²

so

now

cosec²-1-tan²=cosec²-(1+tan²)

cosec²-tan²-1=cosec²-1-tan²

now

cosec²-cosec²-1= -1 -tan²+tan²

so in LHS AND RHS

COSEC² OR TAN² CANCEL OUT DUE TO OPPOSITE SIGN

NOW

-1=-1

LHS=RHS

I HOPE YOU'LL FIND IT HELPFULL ❤️
