WebMar 16, 2012 · Cos theta squared WebAnd then you're gonna have the derivative of the last term, is going to be the derivative of cosine theta times these other two expressions. Well the derivative of cosine theta is negative sine theta, so if you multiply negative sine theta times three theta sine theta, you're going to have negative three theta sine squared theta. did native american women shave

Figure 1: {\bf a} \cdot{\bf b} = ab\cos\theta. If the vectors a and b have magnitudes a and b respectively, and if the angle between them is \theta, then the scalar product of a and b is defined to be {\bf a} \cdot{\bf b} = ab\cos\theta. The scalar product is quite clearly commutative: $${\bf a} \cdot{\bf b} = {\bf b}\cdot{\bf a}.$$ did native north americans have bronze
