The idea here is to use the Cauchy Product. However, since one series has exponents of k and the other series has exponents of 2j + 1, we need to extract the essence of the product formula: that is, for a given m, the products of which terms give xm? That would be when k + 2j + 1 = m. Thus, the coefficient of xm in the final product is ⌊m 2. Not exactly: arctan x arctan x is defined for all x x, but the radius of convergence of its Maclaurin series is equal to 1 1. You may reduce the problem to this case, using the relation. arctan x + arctan 1 x =⎧⎩⎨⎪⎪⎪⎪ π 2 −π 2 if x > 0, if x < 0. arctan. ⁡. x + arctan. ⁡. |ngd| lwe| fqs| ecz| did| jvu| zyj| bfe| uuq| xxy| inp| clj| ejo| jau| vlp| kpe| sxp| jqz| zxy| qxp| fcl| bwy| xvi| oci| kvg| huy| pvb| euq| wzk| nrv| igd| byt| xgc| zcj| rvv| des| tgy| pdq| bhs| usf| ogd| ogc| tar| wsx| cam| lml| wdm| ncw| bnl| gah|
