11. Assuming the curve does not pass through the origin, we can rewrite the parametric equations in polar form : 12. It is shown here both in polar form and in Cartesian form ( via Euler's identity ). 13. For each, the reflection coefficient is given in polar form together with the corresponding normalised impedance in rectangular form. 14. With cylindrical co-ordinates, the motion is best described in polar form with components that resemble polar vectors. 15. This final formula allows complex powers to be computed easily from decompositions of the base into polar form and the exponent into Cartesian form. 16. The probability distribution from which the sample is drawn may be characterized by its moments, which may be expressed in Cartesian and polar form : 17. Bergmann's Rule, which states that polar forms tend to be larger than related ones from warmer climates, has numerous examples in birds. 18. Complex numbers can be entered in either polar form ( using the key ), and displayed in either form regardless of how they were entered. 19. I have read a lot articles on rotation of conic sections but they were all written in terms of the standard form and not the polar form . 20. The polar form requires 3 / 2 multiplications, 1 / 2 logarithm, 1 / 2 square root, and 1 / 2 division for each normal variate.
