Determine sinx tanx-sinx=0 for 0≤ x

Prove: sinx + tanx = tanx (1 + cosx) What I have so far: LS: = sinx + tanx = sinx +...

Prove: (tanx)(sinx) / (tanx) + (sinx) = (tanx) - (sinx) / (tanx)(sinx) What I have so far:...

If tanx=5/12 then what is sinx/2?

How do you solve (1+tanX)/(sinX)using identities? I got cscX

Given sinx= -1/8 and tanx<0. find sin2x

How to prove sec x - tanx sinx= cosx

Limx-0 sinx/tanxsecx+tanx.sinx

Limx-0 sinx/tanx+tanx.sinx

1/sinx - sinx = cosx/tanx

lim (tanx-2x)/(2x-sinx) as X->0 I have no idea how to manipulate the units and isolate something...
