<p>This is actually from the Barron's guide page 38 q. 7:
f(x)= e^x and g(x)=sinx, then the value of (f (<em>little circle</em>) g)(√2) is:</p>
<p>(A) -0.01
(B) -0.8
(C) 0.34
(D) 1.8
(E) 2.7</p>
<p>I have no idea what that lower case "e" means (Iguess we don't study that where I'm from). I found it on the calculator but how do you actually compute a question like this?</p>
<p>This problem is a composite function question. It translates to f(g(sqrt2)). Plug in square root of 2 into sinx and the use the answer you get from that to plug into e^x. This should give you (E), 2.7.</p>
<p><strong>Note, put your calculator into radian mode since the sqroot of 2 doesn’t have a degree symbol</strong></p>
<p>Oh!! Thank you so so much…Putting radian mode was what I missed, I’m totally out of shape in this material. Thanks again!</p>
