Question

tansquare theta -1÷cossquaretheta=1​

Answer 1

ANSWER....

FIRSTLY I GAVE YOU SOME TIPS RELATED TO TRIGONOMETRY SO THAT YOU GET RID OF SOME BASIC PROBLEMS. TRY HIGH ORDER THINKING SKILLS MOSTLY IT WILL REDUCE THE FEAR OF TRIGONOMETRY. NEVER TRY TO LEARN THESE FORMULAS JUST TRY AROUND A 100 QUESTION ON THESE FORMULAS.

$to \: prove \\ \: tan^{2} \alpha - \frac{1}{cos^{2} \alpha } = 1 \\ \\ we \: know \: that \: tan \alpha = \frac{perpendicular}{base} \\ cos \alpha = \frac{base}{hypotaneus} \\ \\ { (\frac{perpendicular}{base}) }^{2} - {( \frac{hypotaneus}{base} )}^{2} \\ \\ \frac{ {perpendicular}^{2} + {hypotaneous}^{2} }{ {base}^{2} } \\ \\ we \: know \: that \: in \: a \: right \: angled \\ triangle \: {p}^{2} + {b}^{2} = {h}^{2} \\ \\ where \: p \: is \: perpendicular \\ b \: is \: base \\ h \: is \: hypotaneous \\ \\ put \: this \: in \: upper \: equation \\ \\ - {( \frac{base}{base} )}^{2} = - 1$

SO THIS IS EQUAL TO -1 NOT TO +1
