if pth term of an AP is q and qth term of an AP is p then prove that its nth term is p+q-1 |
| Answer» \xa0Let first term be a and common difference be d.pth term = a + (p-1)d = q -----(i)qth term = a\xa0+ (q-1)d = p -----(ii)(ii) - (i) gives(q - p)d = p - q or d = -1(i) gives a = q - (p-1)d = q - (p-1)(-1) = q + p - 1Hence,nth term = a + (n-1)d= q + p -1 + (n-1)(-1)= q + p -1 + n +1= p + q - n | |

If tan A=cot B, prove that A+B=90degree |
|
Answer» tanA = tan(90 - B)[ because cotA=tan(90-A)]A = 90 - B (because tan is divided by tan)A + B = 90Hence proved As tanA and cot A are complement of each other So tanA=cot (90°-A)According to the questionCot(90°-A)=cotBIt means 90°-A=BSo A+B=90° Pls aap phir se bta skte h mujhe smjh nhi aaya Tan A=cot B =>Cot (90-A)=cot B =>90-A=B=>90=A+B मुझे पता होता तो पूछता क्यों |
