expand 7sin(pi/(18)(x-8))-0.5

expand

7 sin (\frac{π}{18} (x - 8)) - 0.5

1.21553 \dots sin (0.17453 \dots x) - 6.89365 \dots cos (0.17453 \dots x) - 0.5

Solution steps

7 sin (\frac{π}{18} (x - 8)) - 0.5

Expand

\frac{π}{18} (x - 8) : \frac{π x}{18} - \frac{4 π}{9}

= 7 sin (\frac{π x}{18} - \frac{4 π}{9}) - 0.5

7 sin (\frac{π x}{18} - \frac{4 π}{9}) = 7 (0.17364 \dots sin (0.17453 \dots x) - 0.98480 \dots cos (0.17453 \dots x))

= 7 (0.17364 \dots sin (0.17453 \dots x) - 0.98480 \dots cos (0.17453 \dots x)) - 0.5

Expand

7 (0.17364 \dots sin (0.17453 \dots x) - 0.98480 \dots cos (0.17453 \dots x)) : 1.21553 \dots sin (0.17453 \dots x) - 6.89365 \dots cos (0.17453 \dots x)

= 1.21553 \dots sin (0.17453 \dots x) - 6.89365 \dots cos (0.17453 \dots x) - 0.5

\frac{lo g _{10} ( x )}{( x + 1 ) ^{3}}

(2 x y + 15 y^{2}) d x

(3 x - 9) (2 x + 1)^{'}

2 (x + 10) (e^{x} + e^{- x})

\frac{e ^{x}}{( e ^{x} + 1 ) ^{3}}
