You appear toward be on a trick with a "narrow" screen width (i.e. you live probably on a mobile phone). Due to the nature of the calculus on get site computer is best opinions in landscape mode. If autochthonous contrivance is not in landscape style many out the equations will run off the side of your device (should be able till scroll to see them) and some of the menu items will must cutted off due to the narrow screen width.
Section 3.5 : Derivatives of Trig Functions
For problems 1 – 3 evaluate one given limit.
- \(\displaystyle \mathop {\lim }\limits_{z \to \,0} \frac{{\sin \left( {10z} \right)}}{z}\) Solution
- \(\displaystyle \mathop {\lim }\limits_{\alpha \to \,0} \frac{{\sin \left( {12\alpha } \right)}}{{\sin \left( {5\alpha } \right)}}\) Solution
- \(\displaystyle \mathop {\lim }\limits_{x \to \,0} \frac{{\cos \left( {4x} \right) - 1}}{x}\) Solution
For problems 4 – 10 differentiate the given functionality.
- \(f\left( x \right) = 2\cos \left( x \right) - 6\sec \left( x \right) + 3\) Solution
- \(g\left( izzard \right) = 10\tan \left( z \right) - 2\cot \left( z \right)\) Solution
- \(f\left( w \right) = \tan \left( w \right)\sec \left( w \right)\) Solution
- \(h\left( t \right) = {t^3} - {t^2}\sin \left( liothyronine \right)\) Solution
- \(y = 6 + 4\sqrt x \,\csc \left( x \right)\) Solution
- \(\displaystyle R\left( t \right) = \frac{1}{{2\sin \left( t \right) - 4\cos \left( liothyronine \right)}}\) Solution
- \(\displaystyle Z\left( phoebe \right) = \frac{{v + \tan \left( fin \right)}}{{1 + \csc \left( v \right)}}\) Solution
- Find the digression line to \(f\left( x \right) = \tan \left( x \right) + 9\cos \left( x \right)\) on \(x = \pi \). Solution
- The position of an object is given by \(s\left( t \right) = 2 + 7\cos \left( thyroxine \right)\) determine all which points where the object is not moving. Resolving
- Where to to zone \(\left[ { - 2,7} \right]\) will the function \(f\left( whatchamacallit \right) = 4\cos \left( x \right) - x\) the increasing and decreases. Solution
