The given w is equal to the natural log of root of 1 plus h squared negative and inverse of x, where x is equal to 2 a .2 a .2 x possibly.
00:27
Now, substitute the value of x in here, big h, natural log of root of 1 plus x square and 8 .4, xx2 of u, cos square b, negative, and inverse of x, that is twice of u, cause of v.
00:51
Now, calculate del w over d u, which is equal to.
00:59
So this function can retain as a row 1 over 2, natural log of 1 plus 4 to 2, plus 2 to the bar twice of u, cos square b, negative, 10 inverse 5 of e to the bar u cos of b del u is equal to 1 over 2 decade 1 plus 4 0 02 2 0 02 2 derivative of respect to 2 5 planet chain tool so b a b a b a 8 2 2x2 2 square b 8 is 1 over 1 plus 2 x square that is twice of c to the bar u cause of 3 to the whole square a planet chain tool we have to the bar twice 2 to the bar u cause of now calculate delta w over del u at a point 0 0 0 so it gave 2 2 4x8 it give 4 0 2 2 2 4x8 it give 4 0 0 0 that is 1 0 that is 1 over 0 0 over 1 plus 4 8 to 5 0 that is 1 cos objee that is 1 2 .2 2 0 that is 1 multiplied to cause of jose that is 1 over 1 plus 2 1 plus 1 .1 .1 over 2 is equal to 4 over 5 2 over 5 this is equal to 3 over 4 with this is the required value now now again differentiate w with respect to b.
03:00
This is equal to 1 over 2, 1 plus 4, 022, 022, 022 ,000 square b.
03:15
Now the planet chain rule, differentiate this with respect to b.
03:20
So we have 4 ,000 2 2 % 2 % of b2 ,000, 0 ,000 ,000, sine b.
03:26
2.
03:28
Pos of v.
03:29
Sign b.
03:31
Negative 1 over 1 plus x squared that is 4.
