|dw:1442457266673:dw| remember this CAST rule for signs
Sin theta = -2/9 Tan theta<0 Sec theta = 1/cos theta Tan theta = sintheta/costheta Let tan = -1 -1(costheta)= -2/9 Costheta=2/9 Sectheta=1/(2/9) Sectheta= 9/2
okay
I'm still so confused haha
alright so given sin = -2/9 which is negative 2nd information given is tan < 0 so at which quadrant you should draw right triangle ?
