expand sqrt((1-cos(t))^2+sin^2(t))

expand

(1 - cos (t))^{2} + sin^{2} (t)

2 - 2 cos (t)

Solution steps

(1 - cos (t))^{2} + sin^{2} (t)

Expand

(1 - cos (t))^{2} + sin^{2} (t) : 1 - 2 cos (t) + cos^{2} (t) + sin^{2} (t)

= 1 - 2 cos (t) + cos^{2} (t) + sin^{2} (t)

Rewrite using trig identities

= 2 - 2 cos (t)

(t cos (2 t) + sin (t))^{2}

\frac{d}{d t} ((x) 200 (30 - t^{2}))

\frac{x y ( x ^{2} - y ^{2} )}{x ^{2} + y ^{2}}

(1 + 2)^{6}

(\frac{4}{3} - x)^{2}
