Hisob ilmi bilimdoni

• Sin2α+… =1 Tgα =…
• …* …=1 1+tg2α =
• 1+ctg 2α= … =
• 3 sin π/6 + 2 cos π/6 -- tg π/3 =
• 5 sin π/6 + 3 tg π/4-- cos π/4=

Tenglamalar olami

• 6x+ 11 = 21—6x
• 2)4(x—7)- 2 (x+3)<9
• 5(2-x)- 3x > 2
• 6- 2x > 0
• Ayniyatni isbotlang
• Tg a /(tg a + ctg a) = sin ²a
• Soddalashtiring
• (1+ tg² a)—( sin a – cos a)² / cos ²a
• Tenglama
• 2 cos² x -1= cos² x- 2 sin ²x

Masalalar dunyosi

Masala: Haydovchi yo`l haarakati qoidasini buzdi, soat 12°° da shohko`chaning A nuqtasidan Olmazor ko`chasi tomon burildi.
DAN xodimi chorrahada ya`ni C nuqtada haydovchini to`xtatib qolaoladimi?
