Use the fundamental identities to simplify the expression
how does sinx+cosx when squared equal to sin^2x + 2sinxcosx + cos^2x ?
No restrictions on Θ. cos2Θ-1=0
[0, 2pi) restriction. sinΘcosΘ=cosΘ
[0, 2pi) Restriction. 2sin2Θ=1
Restriction from [0, 2pi). 4cos2x+2sin2x=3
tan2x = sin2x 1+tan2x
1+cosx = sinx sinx 1-cosx
(secx-1)(1+cosx) =tanx sinx
We're using fundamental identities in trig.
I figured this out using my calculator but I need help solving through it without. (cosX)/(1+sinX)+tanX
simplify using trig identities
complete the identity: sin t/(1+sin t) - sin t/(1-sin)= ? 1.) sec (t) csc (t) 2.) sin (t) tan (t) 3.) 1 + cos (t) 4.) -2tan^2 (t)
i need this for my test tomorrow and my teacher isnt asnwering my emails
Prove that 2sin(x) - cos(x) can be written as asin(x-p)
The worksheet deals withb trigonometric identities and we have to prove each of them. I'm stumped on this one. Please, if you could help, I'd highly appreciate it!
Thanks for the help! If you could please show all your work? Thanks again!
