[@nandanisharma8894]

Aapki pahle wali video se samajh mein a gaya tha yah topic
Great sir keep it up😊

[@sujatakumari3602]

A lot of thanks sir ji to explain easily.all concept has been clear.

[@sheetalsoni8252]

Video is very helpful 🙂🙂

[@harishankarsingh1985]

sir, the ans is root2(cos3pie/4 + sin(-3pie/4))
thnx for this video it really helps me alot .....

[@ICSEhelp-mj6dk]

I think it is not correct.

[@IdreesPathan-wg8vk]

​@@ICSEhelp-mj6dki think it is root2 Cos(-pie/4) +(i sin(-pie/4)

From where do you bring pie/4

[@sapnakelshikar8363]

By calculating it in radians

[@aagmatutorialacademy3693]

It has been changed 45 degree into radian. i. e. 45× pie ÷180.

[@cute_lipi_03]

Thank you sir

[@debanjansarma7012]

sir samajh mai nahi aya 😕😥

[@TheRock-ud3so]

1:10

[@indiancomedy3622]

√2[cos(-π\4) +i sin(-π\4)] is the correct answer

[@shilpirajput2788]

Ans: -pi/4

[@jitendraborkar8400]

Someone can explain me how theta = py by 4 comes??

[@psinity]

there is a trigonmetric table where theta(angles) are given in radians here tan theta = x/y, x =1 and y =1 so tan theta = 1/1 ;= 1; tan 45 deg = 1 and tan 45 also equals pi/4; you can search for trigonometric values in radians on google , example 30 deg = pi/6, 60 deg = pi/3 etc etc

[@mayankthakur4955]

Sale sum bhi kar ke dikha
