HELLO DEAR USER!!!!✌️✌️

HERE IS YOUR ANSWER GOES LIKE THIS :

=====================================================================================

YOUR QUESTION:

If tanФ+secФ=∫ then show that secФ=∫²+1/2∫

ANSWER:

tanФ+secФ=∫

tanФ=secФ

squaring on both sides

tan ²Ф=(∫-secФ)²

tan²Ф=∫²-2∫secФ+sec²Ф

sec²Ф-1=∫²-2∫secФ+sec²Ф

∫²-2∫secФ+1=0

secФ=∫²+1/2∫
