Question: Let alpha and beta be first quadrant angles with cos (alpha)=sqrt6/8 and sin (beta)= sqrt7/10. Find the length of tv. Simplify square root of 6* square root of 12. My daughter is learning how to rationalise surds for her school exams. In fact, (a-sqrtb)^2=(a^2+b)-2asqrtb=(a^2+b)-sqrt(4a^2b) The goal here is to reduce sqrt(2-sqrt3) by writing 2-sqrt3 in the form (a-sqrtb)^2, so the square root and the exponent of 2 will cancel one another out. Cancel the common factor of 2 2 and 6 6. Can we prove that there exists no linear combination of $1, \sqrt3, \sqrt6$ that gives $\ Stack Exchange Network Stack Exchange network consists of 183 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. =. We know that $(a-b)^2=a^2-2ab+b^2$, so we can capitalize on the $-2$ in front of the $\sqrt{6}$ and say that Cofunction Calculator: If you have an angle: 45°, then you enter 45 in the Angle box.
