Question

$$\frac{2\ \cos\ 90^{\circ}-35in\ 60^{\circ}-\tan^{2}45}{1+\cos^{4}90^{\circ}-9+on^{2}y5^{\circ}}$$

Answer

$$(2*e*g*cos(90*d)-2100*de*IM*n*g-tan(45*de*g)^2)/(-8+cos(90*de*g)^4+5*de*o*n^2*y*g)$$

Solution


Remove parentheses.
\[\frac{2(\cos{90d})eg-35\imath n\times 60deg-\tan^{2}(45deg)}{1+\cos^{4}(90deg)-9+o{n}^{2}y\times 5deg}\]
Regroup terms.
\[\frac{2eg\cos{90d}-35\imath n\times 60deg-\tan^{2}(45deg)}{1+\cos^{4}(90deg)-9+o{n}^{2}y\times 5deg}\]
Simplify  \(35\imath n\times 60deg\)  to  \(2100ng\imath de\).
\[\frac{2eg\cos{90d}-2100ng\imath de-\tan^{2}(45deg)}{1+\cos^{4}(90deg)-9+o{n}^{2}y\times 5deg}\]
Regroup terms.
\[\frac{2eg\cos{90d}-2100de\imath ng-\tan^{2}(45deg)}{1+\cos^{4}(90deg)-9+o{n}^{2}y\times 5deg}\]
Regroup terms.
\[\frac{2eg\cos{90d}-2100de\imath ng-\tan^{2}(45deg)}{1+\cos^{4}(90deg)-9+5deo{n}^{2}yg}\]
Collect like terms.
\[\frac{2eg\cos{90d}-2100de\imath ng-\tan^{2}(45deg)}{(1-9)+\cos^{4}(90deg)+5deo{n}^{2}yg}\]
Simplify  \((1-9)+\cos^{4}(90deg)+5deo{n}^{2}yg\)  to  \(-8+\cos^{4}(90deg)+5deo{n}^{2}yg\).
\[\frac{2eg\cos{90d}-2100de\imath ng-\tan^{2}(45deg)}{-8+\cos^{4}(90deg)+5deo{n}^{2}yg}\]
