2(sin 6?+cos6?) - 3(sin4?+cos4?)+1 = 0
Ans: (Sin2?)3 + (Cos2?)3-3 (Sin4?+(Cos4?)+1=0
Consider (Sin2?)3 +(Cos2?)3
⇒(Sin2?+Cos2?)3-3 Sin2?Cos2?( Sin2?+Cos2?)
= 1- 3Sin2? Cos2?
Sin4?+Cos4?(Sin2?)2+(Cos2?)2
= (Sin2?+Cos2?)2-2 Sin2? Cos2?
= 1- 2 Sin2? Cos2?
= 2(Sin6?+Cos6?)-3(Sin4?+Cos4?) +1
= 2 (1-3 Sin2? Cos2?)-3 (1-2 Sin2?+Cos2?)+1
An orange has a diameter of 3 inches. Evaluate the volume of one orange. (π = 3.14) a. 9.42 in 3 b. 113.04 in 3 c. 28.26 in 3 d. 14.13 in 3 d. To determine the
The sum of -4 and a number is equal to -48. What is the number? Let x = the number. Because sum is a key word for addition, the equation is -4 + x = -48. Add 4 to both sides o
