solvefor x,1=2x+cosx

解答

求解

x, 1 = 2 x + cos (x)

解答

x = 0

+1

度数

x = 0^{\circ}

求解步骤

1 = 2 x + cos (x)

交换两边

2 x + cos (x) = 1

Find the interval where both equation sides share the same range:

0 \leq x \leq 1

0 \leq x \leq 1

Find the difference function:

2 x + cos (x) - 1

2 x + cos (x) - 1

Extreme points of

2 x + cos (x) - 1

at

0 \leq x \leq 1

(0, 0), (1, cos (1) + 1)

Find the x-axis intersections

x = 0

12 a - 7 a = 9

solvefor y,8y=2x-4

so l v e f or y, 8 y = 2 x - 4

9 x + 6 = 3 (2 + 3 x)

x + 3 = 3

- 5 x = 11 - 2 (4 x - 2)
