Chalk is a sedimentary rock, primarily composed of limestone and formed from the microscopic skeletons of marine organisms. Unlike granite, basalt, and pegmatite, which are all igneous rocks formed from cooled magma or lava.
If sinAo = (√3/2), then find the value of (sin245o + cos230o) × A ÷ 5 given that 0 < A < 90...
If cos²α + cos²β = 2, then the value of tan⁴α + sin⁸β is
Find the value of (1 - sin2q) X (secq + tanq) X (secq - tanq) X cosec2q
If cos(2θ) = 1 - 2sin²(θ) and tan(θ) + cot(θ) = k, find the value of k when sin(θ) = 3/5.
The value of (sin 60 º cos 30 º - cos 60 º sin 30 º) is equal to:
Find the value of tan(75°) using the identity for tan(A+B).
