Question is if i n equal to court full power and DC and I not + 1 + 2 of 2 EP 28 the Sinai i10 equals to a u + you to the power 2 + this is this value is up to the you to the power 9.9 constant where the value of you is given context then we have to choose which option is first thing to solve this question we will write the equation which is given in the question why is equals to integration of cot power in DF and write it like on splitting call to the power n i can write it caught in - 1 x minus 2 X into cos square x I have expected this because when we add this and - 2 + 2 into will be cancelled out we got to the power NDA now as we know thatĪs we know that cos square x cos square x is the value of 1 + cot Square X so I can write here I equals to integration of cot and -2 power x into in place of cot Square X I can write causes square minus one which is equal to the value of what is 9 when we put it it I will get here in place of cot square it cause it Square x dx now on differentiating integrating I get integration i n is equals to I can write it called when we multiply disturb to these Tuta cot x to the power n minus 2 into korzok Square x dx this is our first term second term when X is -1Ĭourt power n minus 2 x dx it is clear that the value of n is caught and then the value it will be set to be caught our eye and -2 because I N is called to the power n minus 2 is court and -2 now finally we can write this equation like this I N when transform transform in this equation to the left side I get iron plus i n minus 2 equal to the remaining term will be only this so I can write it integration of cot x to the power n minus 2 into cos square x dx now to solve this let cot X = 2 X equals to see it means on differentiating of cortex I get minus cos square x dx equal
