Question

jim_thompson5910  help me:(sin A-cos A+1)/(sin A+cos A-1)=1/(tan A+sec A)

anonymous · Answer

@jim_thompson5910 .

anonymous · Answer

1/(sina/cosa+1/cosa)

jim_thompson5910 · Answer

See what you get when you combine sina/cosa+1/cosa

jim_thompson5910 · Answer

I'm not sure how you'd turn it into the left side though

anonymous · Answer

to get in terms of sin ,cos.if it is wrong?.explain

anonymous · Answer

(sina-cosa+1)/(sina+cosa-1)*(sina-cosa+1)/sina-cosa+1)

jim_thompson5910 · Answer

hmm that might work, see what happens when you expand it out

anonymous · Answer

2/sina cosa+

anonymous · Answer

(sin^a+cosa sina -sina-cosa sina-cos^a+cosa +sina+cosa+1)/(sin^2a+sinacosa+sina+cosasina+cos^2a+cosa-sina-cosa-1)

jim_thompson5910 · Answer

definitely a mess, but maybe a few things cancel?

dumbcow · Answer

wait this is not an identity ... are we solving for "a" ?

dumbcow · Answer

please specify whether the problem is to verify an identity or solve for a variable

you can waste a ton of time trying to match both sides when its actually impossible :)
