\frac{d}{dx}(tan^{3}x) = \frac{d}{dx}(tanx)^{3}
= 3(tanx)^{2} \cdot sec^{2}x

\therefore \frac{d}{dx}(tan^{3}x) = 3tan^{2}x \cdot sec^{2}x

What is the greatest common factor (GCF) of 15 and 64? <br>1. (3) <br>2.(4)<br>3.(8)<br>4.(1)​
omeli [17]
It’s 1.

Explanation: you need to find the greatest factor that works out for them both. You can cross out 4 and 8 because no other whole number can be multiplied to get 15, and it’s not 3 since you can’t multiply it with a whole number to get 64. 1 works for them both.
