Hi. Can you verify the following: (cosθ) / (sinθ – 1) + (cosθ)/ (1 + sinθ) (1 / cos^2θ) – (2) (1/cos^2θ) (sinθ / cosθ) + (sin^2θ / cos^2θ)

Can you explain what is the answer if I encounter(sinθ – 1)? Can you also teach me how to get the LCD of cos^2θ and cos^3θ? Thanks.

Hi. I am reposting this. Can you verify. Thanks. (cosθ) / (sinθ – 1) + (cosθ)/ (1 + sinθ) = -2tanθ (1 / cos^2θ) – (2) (1/cos^2θ) (sinθ / cosθ) + (sin^2θ / cos^2θ) = (1 - sinθ) / (1 + sinθ)

Oops, sorry. The increase is 54 and not 5y. Typo. So the real word problem is "A two-digit number is increased by 54 when the digits are reversed. If the sum of the digits is 12, find the number."

Yes! I got the same answer. Thanks.

Oooops. Its this one. Sorry. (cosθ) / (sinθ – 1) + (cosθ)/ (1 + sinθ) = -2tanθ (1 / cos^2θ) – (2) (1/cos^2θ) (sinθ / cosθ) + (sin^2θ / cos^2θ) = (1 - sinθ) / (1 + sinθ)
