If sinx = 3/10, then what is the value of tan x + cot x = ?
\(
\frac{100}{3\sqrt{91}}
\)
\(
\frac{100}{2\sqrt{83}}
\)
\(
\frac{100}{7\sqrt{95}}
\)
\(
\frac{100}{3\sqrt{85}}
\)
Solve the given expression.
\(
\frac{\sec^{2}(90^\circ-\theta)-\cot^{2}\theta}{2\left(\sin^{2}35^\circ+\sin^{2}55^\circ\right)}
\)
