In elementary algebra, the binomial theorem describes the algebraic expansion of powers of a binomial According to the theorem, it is possible to expand the polynomial n into a sum involving terms of the form axbyc, where the exponents b and c are nonnegative integers with b c = n, and the coefficient a of each term is a specific positive integer depending on n and b For example, 4 = x 4 4 x 3 y 6 x 2 y 2 4 x y 3 y 4 {\displaystyle ^{4}=x^{4}4x^{3}y6x^{2}y^{2You can solve as many equations as you like completely free If you need detailed stepbystep answers you'll have to sign up for Mathway's premium service (provided by a third party)Divide x, the coefficient of the x term, by 2 to get \frac {x} {2} Then add the square of \frac {x} {2} to both sides of the equation This step makes the left hand side of the equation a perfect square y^ {2}xy\frac {x^ {2}} {4}=4x^ {2}\frac {x^ {2}} {4} Square \frac {x} {2}
This can be viewed as a version of the Pythagorean theorem, and follows from the equation x 2 y 2 = 1 for the unit circle This equation can be solved for either the sine or the cosine sin θ = ± 1 − cos 2 θ , cos θ = ± 1 − sin 2 θ {\displaystyle {\begin{aligned}\sin \theta &=\pm {\sqrt {1\cos ^{2}\theta }},\\\cos \theta &=\pm {\sqrt {1\sin ^{2}\theta }}\end{aligned}}} · See the explanantion This is the equation of a circle with its centre at the origin Think of the axis as the sides of a triangle with the Hypotenuse being the line from the centre to the point on the circle By using Pythagoras you would end up with the equation given where the 4 is in fact r^2 To obtain the plot points manipulate the equation as below Given" "x^2y^2=r^2" ">" "x^2y^2X^45x^24=0 \sqrt{x1}x=7 \left3x1\right=4 \log _2(x1)=\log _3(27) 3^x=9^{x5} equationcalculator y=x^{2} en Related Symbolab blog posts Middle School Math Solutions – Equation Calculator Welcome to our new "Getting Started" math solutions series Over the next few weeks, we'll be showing how Symbolab
