[00:03:47]mus 4 m + - 6 n / m + n Fore musal 5 51 mal into 51 option.

[00:04:58]Next. What is the value of sin square2?

[00:05:13]1x square 18 sorry a 1sec Next square 1x roo<unk> / 2. So sin 60° by 2<unk> 3x2 by 2 square 90° theta cos theta sin square 182 sin square 72 sin square 72°. Okay. Plus square 182° square 90° 90° us the cosine 90° 90° theta 72 72° 2<unk> over 3 / 2 square 1x roo<unk> / 3 1x 10° 1 by 3.

[00:08:16]Next.

[00:08:26]Seek 1 by cos theta. A= 1 / cos A into 1 - sin A.

[00:09:11]1 + sin A into 1 - sin A 1 A + B into A square us A / A cos 1 - square [snorts] sin square sin square a + cos² a = 1 square 1 - sin square a cos a cos a cos square next number >> [snorts] >> Mn.

[00:11:02]Okay. [snorts] More 3.6 cm 3.6 cm.

[00:11:27]Uh 3.6 cm 3.6 3.6.6.6 + 3.6 7.2 2 cm.

[00:35:08]Fore 2 square into 7.

[00:35:39]7 9 by 2 by 2 into 7 4 A x + b + c + a x + b x² + c x + 1 + alpha alpha beta alpha beta gamma 1 + alpha into 1 + beta into 1 Alpha plus beta plus gamma by a beta plus beta into gamma plus gamma into a beta into gamma into minus d by a 1.

[00:37:36]Next one.

[00:37:51]A plus into beta beta plus 1 into beta 1 alpha beta plus 1 + beta plus alpha plus alpha into beta 1 + alpha beta beta gamma beta gamma plus alpha gamma plus alpha beta gamma beta single alpha plus beta plus gamma. Okay.

[00:38:55]Next. Alpha beta plus beta gamma plus alpha gamma alpha beta gamma plus c by a plus alus d by A b + c minus d a minus b plus c minus d opt a minus b + c minus dt 3 1 by 1 by 3 x - 3 x 1 by 3 X² X into 1x 3 - 1x 3x - 3 into x - 3 x - - 3 into 1 by 3 + So 3 into 1 by3 - 1 by 3 x - 3x 3 into 1x 3x - 3 into 3x + 3 into 1 3x² - x 3x² - x + 3 x² - 10 x + 3 x + b x + c x + b x + c 3 x - 10 x + 3 [snorts] square to a square x to b 10us.

[00:42:20]Next.

[00:42:33]A12 A1 by A2 equal to B1 by B2 C12 Y - 3 Y += 3 2X - 3 Y = 9 y - 6x = 2. Okay. 9x 9 y - 6x 9 y - 6x = p by 2. Uh okay.

[00:43:13]- 6x + 9 y = 2 a1 b1 c1 a2 b2 c2 aus b1us b not equal to c1 32 p by 2 - 1 P into P= 3 into 6 PUS 18 not equal to Foreign
