prove cos(x)+sin(x)=tan(x)+1

prove

cos (x) + sin (x) = tan (x) + 1

False

Solution steps

cos (x) + sin (x) = tan (x) + 1

Show that the two sides are not equal

For

cos (x) + sin (x) = tan (x) + 1

plug in

x = 1

cos (1) + sin (1) = 1.38177 \dots

cos (1) + sin (1)

Refine to a decimal form

= 1.38177 \dots

tan (1) + 1 = 2.55740 \dots

tan (1) + 1

Refine to a decimal form

= 2.55740 \dots

The two sides are not equal

\Rightarrow False

csc (2 θ) = \frac{( csc ( θ ) sec ( θ ) )}{2}

\frac{sin ( a ) + cos ( a )}{cos ( a )} = tan (a) + 1

cos (5 \cdot π) = - 1

\frac{4 sec ( x )}{3} = \frac{4}{3} sec (x)

(22 cos (x))^{2} + (22 sin (x))^{2} = 2 2^{2}
