expand-1/((3-1)^2)-cos(3-1)

expand

- \frac{1}{( 3 - 1 ) ^{2}} - cos (3 - 1)

- \frac{1}{4} - cos (2)

Decimal Notation

0.16614 \dots

Solution steps

- \frac{1}{( 3 - 1 ) ^{2}} - cos (3 - 1)

Subtract the numbers:

3 - 1 = 2

= - \frac{1}{2 ^{2}} - cos (2)

2^{2} = 4

= - \frac{1}{4} - cos (2)

2 π ((3 + \frac{2}{π}) \cdot \frac{π}{2} + (2.66666667) \cdot \frac{1}{2})

(6 sin (θ) + 5)^{2}

csc (x) (csc (x) - cos^{2} (\cdot csc (x)))

(2 - 3 i)^{5}

(\frac{3 a}{2 b} + \frac{4 b ^{2}}{5})^{3}
