d=7.2sec(*sin(30-20))

解

d = 7.2 sec (\cdot sin (3 0^{\circ} - 2 0^{\circ}))

解

d = 7.2 sec (sin (3 0^{\circ} - 2 0^{\circ}))

解答ステップ

d = 7.2 sec (sin (3 0^{\circ} - 2 0^{\circ}))

さらに簡約できない

d = 7.2 sec (sin (3 0^{\circ} - 2 0^{\circ}))

a/(sin(44))= 9/(sin(66))

\frac{a}{sin ( 4 4 ^{\circ} )} = \frac{9}{sin ( 6 6 ^{\circ} )}

solvefor c,sec(45+a/2)sec(45-a/2)=2sec(a)

so l v e f or c, sec (4 5^{\circ} + \frac{a}{2}) sec (4 5^{\circ} - \frac{a}{2}) = 2 sec (a)

cos^2(x)=1+cos^2(x)

cos^{2} (x) = 1 + cos^{2} (x)

solvefor c,sin^3(x)+sin(x)cos(x)+cos^3(x)=1

so l v e f or c, sin^{3} (x) + sin (x) cos (x) + cos^{3} (x) = 1

solvefor t,tan(x)tan^2(x)=1

so l v e f or t, tan (x) tan^{2} (x) = 1
