Just a short trick for everyone.... To simplify iota to the power some big number like 70,90,123,1125 or anything just divide the power by 4 and the remainder will be your new iota's power 😊
ha sir 1:17:56 quection mere periodic test 1 and tution ki 3 exams me aaya hai trust me guys this is very important if anyone agree then please like so new students come to know this question's importance
1:39:15 the denominators are (2+5i) and (2-5i) so in the denominator by (a+b)(a-b)=a^2-b^2 so the denominator of the answer will be (2)^2-(5i)^2 which is 4+25 i.e., 29 therefore final answer should be -8/29
Sir at 1:42:32 , the question would be x²+ax+b=0 and the ans of that question is a)-4 , not 0 As the equation in the end is (b+a)i(2+a)=0+0i Therefore, a+2=0 ie a=-2 and similarly, b=2 Hence, a-b=-2-2=-4, which is the final answer

1:42:20 Sir this question is Example 27 of Exemplar book, and it states that if 1- i, is a root of the equation x² + ax + b, where a, b belongs to R, then find the values of a and b.
Please tell that we take sign also int the root because value of complex part is -1/2 but when it comes under square root what we take -1/2^ or without sign 1/2^ Please reply soon I need your help
literally sir , its a awesome one shot , you cover all topics and most imp ques of ncert and pyqs ,thankuuu ssir , kl mera half yearly h its really helpful for me
sir ji question is not wrong, minus hi hoga, one root will be 1-i and one will be 1+i (since both roots will be conjugate of each other) so ans is -4 (A), 1:43:18

z = x+iy
|x+iy-3| = |x+iy+3|
| ( x-3)+yi | = | (x+3)+iy) |
√(x-3)² + y² = √ (x+3)² + y²
Squaring both sides
x²+9-6x+y² = x²+9+6x+y²
-6x=6x
-6x-6x = 0
-12x = 0
x=0
z = 0+iy
Z lies in y axis

1:01:09 x=3, y=-3ans
Sir at 1:42:32 , the question would be x²+ax+b=0 and the ans of that question is a)-4 , not 0
As the equation in the end is (b+a)i(2+a)=0+0i
Therefore, a+2=0 ie a=-2 and similarly, b=2
Hence, a-b=-2-2=-4, which is the final answer
