sin2x=2sinxcosx Tangent Double-Angle Identity: tan2x=2tanx1−tan2x Pythagorean Identities: sin2x+cos2x=1 tan2(x)+1=sec2(x) Answer and Explanation:1 Since we are given with the value oftanx=34, we can solve forsecx. ...
Verify the identity: \frac{\sin x + \sec x}{\sec x} = \sin x\cos x + 1 Verify the identity: \dfrac{\cot x}{\sec x} = \csc x - \sin x. Verify the following identity: sec x - cos x = sin x tan x Verify the following identity. sin 2x(tan x + cot x) = 2 ...
sin2x=1−cos2x2 This identity allows us to rewrite the integral. 2. Rewrite the Integral: Substitute the identity into the integral: ∫sin2xdx=∫1−cos2x2dx This simplifies to: =12∫(1−cos2x)dx 3. Split the Integral: Now we can split the integral into two parts: =12(∫1dx...
Tennessee's Pterotrigonia fossils are found mainly in the state's Coon Creek Formation, a 73 million-year-old, 240-acre seafloor deposit containing nearly 700 preserved species located some 90 miles east of modern-day Memphis. So important is the species to the state's geological identity tha...
